Im relatively new to boat motors, but learning quickly, thanks to the likes of Iboats and a few tech manuals.<br />I own early 80's Merc and upon reading through the Clymer manual in my spare time :( <br />(Yes.... get a life Andy...)<br /><br />I noticed that a lot of testing can be done by using a multimeter (ohms, volts, etc).<br />Are there any tricks or techniqies associated with these units? Or a specific type that particularly suits outboards ??

Re: Multi testers

If not familiar with multi meters then get a digital, easier to use and read. The analogs can be more precise but need to usually read several levels on the dial for different settings. You don't want to spend alot if you plan on taking current measurements as can fry if hook up wrong. <br /> If have a manual for motor follow the test directions and remember that many components need to be isolated from the engine to get correct readings. <br /> As always read the directions that come with the meter. These multimeters have been around along time and are simple to use if you take your time. Once you have done a few tests it will be no problem.<br /> Hope this helps.

Re: Multi testers

Thanx Telmanmn ;) <br /><br />Most tests on the Merc seem to use the (Ohms) gauge. For instance, Trigger, rectifier, stator etc. This, I assume is a measure of resistance and in just about all cases, you do need to isolate the component and disconnect the wiring.

Re: Multi testers

Hi Andy....Tel got some good points on the digital meters. Now the other side, I myself prefer the analog or dial meter. I like being able to see the needle deflection at distanace. Also, a peak reading volt meter is great for reading coil and power pack (switch box on Mercs) outputs. What it boils down to is what is preferred by the user. Tel prefers digital, I prefer analog. We both can probably do just as much as the other can.<br /><br />What ya might do is take a trip to Sears ( yea, Sears) and check out their meters. Play with them a little and see what they do. My help ya make a choice.

These folks make some instruments specifically for testing outboard engines. Kinda high-dollar but good stuff.<br /><br /> Stevens Instruments <br /><br />c/6<br /><br />Hooty

Re: Multi testers

Thanx Guys<br /><br />I'm sorta on the other side of the world.. so some of these retailers here are a bit foreign to me.<br />But I get the general idea and will look around. :p
