So been a wile, having a kid takes up a lot of your time. So ready to start working on this boat again. Cant seem to find non oil filled 12v motorcycle coils. As you can see in the images they are both around 3.4 to 3.5 ohms and almost 9ohms on the spark side. The cracked one has 0 ohms on spark...
Here’s some pictures of them. One the secondary side, spark plug wire side doesn’t ohm out on one so that is bad. Other one seems to be good and ohms out at 8.97 and both prime sides ohm out at 3.4 and 3.5 ohms
They didn’t have any resistors on the outside of them. (I think some of the 12vs had inside resistors to make them 6v) So maybe a 3 ohm 12v motorcycle one would work. I’ll order some and check with a spark gap tester to see if they have spark.
I’ll check the ohms of the good coil. One is cracked and is bad I know that. I see some are 1.5 and others are 3 ohms. Need to find that out before I buy one
Okay I’ll probably get a motorcycle one. Now should it have the resister inside or no? If I spark test one with and without the resister it should still spark right?
I like the idea to cover it in heat shrink then plastydip, or liquid electric tape to seal it that’s great!
So we are restoring our family boat with motor and trying to bring it back to life. The question I have it’s using the Mercury-Mercruiser 85-818076A2 coil I found online it should have a 9,400-11,700 Ohms. One is cracked and the other seems to be okay. I looked online and they are $120-180...
Hydro electric shift Johnson for the 65hp and 100hp motor I have. Work around, simple relays and Arduino setup.
Here's pictures of my setup. I have a 65hp, 100hp and a 140hp Johnson... On my 65 hp I put the Johnson electric shift dumb 12v relay switchs and I drilled a hole and put in a screw...
