Wiring for teleflex Tacho, OMC variant. any ideas Mr Schematic??

[Franki]

Hi guys, I have two teleflex gauges, one is just the standard job with the normal poles..<br /><br />and the other is a flasho version with a wiring loom coming out and only a gnd pole.. the front has warning lights for:<br />Low Oil,<br />Chk Eng,<br />Hot,<br />No Oil<br /><br />The loom has wires of the following colours.<br /><br />1 Red,<br />2 Black<br />3 Grey<br />4 Yellow<br />5 Green<br />6 Blue<br />7 Orange<br />8 White.<br /><br />The plug is numbered, and I have put the numbers next to their relevant color wire.<br /><br />Anyone have any ideas what the color codes relate to? I'd assume grey is the tach signal wire, but who knows?<br /><br />brown should be for the hot light, but there isn't a brown wire.<br /><br />any tips would once again be fantastic <br /><br />regards<br /><br />Frank

Frank go here for the telex wiring http://www.tflx.com/PDF/99320.pdf <br /><br />I just installed a tach on my Johnson (that does not sound right LOL ) and I found the grey wire in the control box along with a hot and ground. The plug that was in the spot had plastic pins and I replaced them with metal pins w/wires. My entire tach wiring goes from the control box to the dash (less than 3 feet of wire)<br /><br />Telex also sells the sending units for most of thier guages.<br /><br />Good luck. <br /><br />Bob_VT with a Tach on his Johnson LOL <br /><br />BTW Frank I have a Evinrude/Johnson 48-235 1973-1990 with wiring diagrams.<br /><br />Schematic will probably help out more

Franki<br />Don't have a code for you, but I'll bet the first three are for the tach. The others are probably for the indicators and illumination. Are the indicators bulbs or led's. If they are bulbs, measure the resistance between 2-black and 4-8. If they all read the same (20-50ohms)then I'd bet they are all bulbs. Verify this by powering them up one at a time to determine what they are.

Hi Guys,,<br /><br />firstly, bob_vt, you didn't give any readings from the tacho on your "johnson" so I am wondering if WOT is still painful ??? <br />Also, I have also already made a control box to dashboard loom, and it has all the power, temp tach signal and I also added another for an external temp guage.<br /><br />Schematic,, the warnings are either leds, or some seriously small bulbs.... (kidding, they look like LED's to me.)<br /><br />Here are some pics that might make things clearer. (I love having a digital camera and my own web server... <br /><br />

<br /><br />and the back:<br /><br />

<br /><br />As you can see, the poles normally on the back were replaced by the loom.<br />So if we assume that the black, red and grey are the earth, power and signal for the tach, that means the rest would be for the illumination and the lights.. (I thought it better to ask cos I really don't want to risk damaging this thing.)<br /><br />Incidently, that pdf file didn't cover this tach,, I assume it was made for lund by teleflex for specific application...<br /><br />regards<br /><br />Frank

Re: Wiring for teleflex Tacho, OMC variant. any ideas Mr Schematic??

I agree w/Schematic the first three are probably the tach with the gray being the sending wire. I would also bet that the hot and ground also control the backlight inside the tach so the light is on as long as the key is on. With the led warning lights make me consider that the tach was designed for a 4 stroke? (pure guess)<br /><br />Have a great day.<br /><br />Bob

Re: Wiring for teleflex Tacho, OMC variant. any ideas Mr Schematic??

Yeah, I think the whole gauge was designed for a inboard or an outboard... or a 4stroke outboard, (do OMC even make one?)<br /><br />Anyway, they are not really that important... I will figure them out..<br /><br />I hate the fact that the lights are on all the time, thats the way the whole dashboard is and its just not necesssary.. I'd rather turn them on manually..<br /><br />regards<br /><br />Frank

Re: Wiring for teleflex Tacho, OMC variant. any ideas Mr Schematic??

if you power up the red and black, the indicators come on? If so, try grounding one of the 4-8 wires. Either ground or live will turn them off....try grounding first(do your grounding and feeding through a testlight). It will limit the current and reduce the chance of damage.

Re: Wiring for teleflex Tacho, OMC variant. any ideas Mr Schematic??

Hi again Mr Schematic Bob_vt and all..<br /><br />I did the tests, you are right about black and red, they are power and earth, (there is an earth pole on the back as well..) the tach returns to zero when power is applied.. (it sits at around 800rpm with no power.)<br /><br />However, I have only been successful in getting the backlighting working.. the power for that is actually the two poles on the back (one of which is gnd.)<br /><br />So, while the unit is powered (and backlit), applying negative or positive to any of those other wires has no result.. and the lights do not come on with just power..(red and black)<br /><br />Unless the unit needs to get a signal on the grey wire before it lights up the warning lights, (and then turnes them off when they checkout...)<br /><br />I just dont know, and there is no way to pull the unit apart to have a look at the layout..<br /><br />any tips? or should I try emailing tech support of teleflex??<br /><br />regards yet again, <br /><br />Franki

Incidently, here is a photo of the dash board I am wiring up.. so you know what all your suggestions are going towards... <br /><br />

Stumped?? I think e-mailing teleflex is the right thing to do. You might be able to adapt the un-used lights for other features....or just hook them all to a toggle switch labeled "PANIC"<br /><br />Bob

The guage or dash ass'y you bought is for an OMC engine that has "SystemCheck" as part of the onboard electronics. This guage MAY not work with older engines. However I would think you could pick out the three leads needed (for tach.)with Teleflex help. I doubt you'll get the other functions to work.<br /><br />Did you buy this from KV Enterprises?

Re: Wiring for teleflex Tacho, OMC variant. any ideas Mr Schematic??

Hi Bob,<br /><br />Yeah, I was thinking that I could use the Hot by hooking it to the tan wire from the head, (or from the temp gauge).. and I could probably rig up something to the chk engine light as well.. <br />Low oil and No oil will have to wait will I get a DFI two stroke... <br /><br />Oh well, if Mr schematic has nothing to say on the subject, then teleflex is the next stop..<br /><br />regards<br /><br />Franki

Re: Wiring for teleflex Tacho, OMC variant. any ideas Mr Schematic??

Hi Djohns, <br /><br />I did get this tack and another one from Kv-Enterprises.. the other one is normal, and I already have the tach side of both working already.. (the one in that dash is the normal teleflex, both have the pole switch on the back.. <br /><br />So I can make both work as tachs, I was just hoping to get some of the warning lights working as well, (like the "HOT" light..) but its no biggie.. I will get a newer Johnson one day, so I'll be keeping this tach for that boat and just use the normal one for this motor..<br /><br />One other thing I was wondering,, how do you change backlight color on these things? I thought they'd use colored boots over the globe, but they don't.. so I am assuming I can't change the backlight color?<br /><br />regards<br /><br />Frank

Re: Wiring for teleflex Tacho, OMC variant. any ideas Mr Schematic??

Franki,<br /><br />Remember, your temp sensor in the head is a "grounding" circuit. In other words, you GROUND it to check it. I see where you are heading with your ideas. You would have to run a hot wire to the light (hot with key on only) in the guage and the other side to the sensor. That way if the head gets hot, it completes the circuit.<br /><br />Is this going on a VRO engine? You could do the same with the low oil and no oil sensors-I believe. <br /><br />How was the service from KV?

Hi again, <br /><br />Val at KV was great, and cheap... <br /><br />He shipped a huge dash all the way to Australia.. pretty cool I thought.. <br /><br />Anyway.. I know that the tan wire sends a negative.. but I can change that with a relay if necessary.. problem is, nether a positive or a negative turns the warning lights on.. (unless the tach has to be receiving a signal (grey wire) at the time for them to work.. )<br /><br />Anyway, its really just for yuppy value anyway.. I have a full sized car horn hooked via relay to the tan wire, and an external temp guage.. so I don't really need the warning lights.. it would just be cool is all <br /><br />No, I don't currently have a VRO or DFI engine, I have an old premix job.. (otherwise I'd really want to get the lights workin and monitor the VRO..)<br /><br />If you are thinking about getting a gauge from kv-e.com, then go for it.. Vic seems a nice guy.. <br /><br />The ******* (joke) has an amazing way of putting boats together on the cheap.. he has alot nicer equipment then me.. (then again, thats not hard right now. <br /><br />The dash looks so much more modern then the rest of the boat that I have ripped out the entire interior of the boat for a refit.. find out if I am still has good at it as I used to be.. <br /><br />now I have to find some cheap marine ply.. <br /><br />rgds<br /><br />Frank.

I also bought a Teleflex Tachometer and Trim Guage for a yahama 703 control but don't know the wiring code for the control. Help would be greatly apprecaited ps there's a black, red, green and yellow also 2 green wires together 2 Blue with red stripe together and 2 red together on the control
