Title: Electrical issue , I think ...
Post by: beerjet on February 19, 2007, 01:50:38 PM
An electrical gremilin? Not an electrician? I am.  ;D

I've rewired over 10 complete cars/trucks and have been professionaly electrically troubleshooting for 16 of my 20 year career. Where you at?
Sorry I didnt get back to you but I had breakfast and then a nap ensued . It was running like crap and sputtered often and on the way back everything just quit, electrical and mechanical. I had a test light handy so I took it to the junction block and Nothing had power since I would turn the key on and off and it was like I didnt have a battery hooked up . Absolutly no power .

So being the genius that I am , I took a huge flat blade screw driver to the starter at the solenoid and the motor would jump over so I figured there was at least power to there so I turned to key off and then turned it back on and it fire back up  ???  ???  ??? . It had done this to me before once so this is new . The only thing I can think of is that its the starter , my old trusty delco starter has finally decide to let me down after several years of the worst abusive service . I dont know that for sure , but I can only hope since I have a marine starter on stand by and that has let me down before soooo....

The first thing I would check would be the ground wire. That screwdriver trick is more likely to force the ground to work rather than a key switch or stereo or... If you have a meter check the battery voltage at the battery and then check the voltage at the ground wires and the voltage at the starter. Wiggle the ground wires around to see if it changes anything. Is there a battery isolator/switcher? If so that's where I'd go after checking the ground wires. You'll be looking for any drop in voltage. After the battery isloator/switcher check I'd go to the key switch itself. You'll be comparing the key switches input voltage to the key switches output voltages. My friend's Eliminator did the exact same thing that your boat is doing and it was a bad ignition switch. If you don't have a volt meter go to radio shack and spend $5 to get one. It doen't matter if it's very accurate because you'll be looking for a difference in voltage - not a correct amount of voltage (i.e.: 12.3 volts). Rod.

Thanks . I'll invest . This is all new to me since electrically I havent changed anything so we'll see what happens .

It was a breaker switch that was out of sight . You know how the rest of it goes.
