lastbrunneng Posted July 22, 2009 Share Posted July 22, 2009 Hello, So, following a heavy rain last night, my 76 280z wouldn't start this morning. Basically, anytime a draw (including turning the key to any position or just the dome light coming on when the door is open) is placed on the battery the in dash voltmeter drops to 8, then continues to fall until zero volts. So far, when I turn of off the draw (say by closing the door) the volts will go back to 8 then slowly raise to 12. The car obviously won't start like this. I tried taking all the fuses out and the problem persisted, indicating to me that the problem is before the fuse box. I'm sure this is related to the moisture from the rain. I'm a bit stumped, though, that there could be a short to ground which only drains the battery when another draw is placed. Electrical diagnosis is not my specialty, I took a class at the local Vocational but I'm hoping someone can direct me to a likely problem or a good diagnostic procedure. Until then I'll be checking connections. Thanks for any possible help. Quote Link to comment Share on other sites More sharing options...
m4xwellmurd3r Posted July 22, 2009 Share Posted July 22, 2009 Your fuesable links on the passanger side of the car probably got filled with water, and are now corroded. Unplug them and take a pick of some sort to clean them off. That's what happens most of the time. Quote Link to comment Share on other sites More sharing options...
lastbrunneng Posted July 23, 2009 Author Share Posted July 23, 2009 Thank you very much, that's exactly what it was. And like a newb I never even considered the fusible links. I really appreciate the help getting my baby back on the road! Quote Link to comment Share on other sites More sharing options...
m4xwellmurd3r Posted July 23, 2009 Share Posted July 23, 2009 and now i'm stuck with a stumbling problem more likely than not, caused by teh recent rain we've had out here, compounded by teh recently humid days. which really BITES. I hate tracking down these gremlins. I was really hoping that my fuel filter was dirty again. Quote Link to comment Share on other sites More sharing options...
jhm Posted July 30, 2009 Share Posted July 30, 2009 Max- Ever get your problem solved? If not, check if there's moisture inside your distributor. Very possible after a heavy rainfall, and can easily cause the motor to stumble and run poorly. Fortunately, very easy to solve -- best technique I've found is to pop the distributor cap and thoroughly blow out the internals with compressed air. Good luck and happy motoring! jhm Quote Link to comment Share on other sites More sharing options...
m4xwellmurd3r Posted July 30, 2009 Share Posted July 30, 2009 Yeah, it was actually the fuel line. The filter I have in the rear was clean, but I guess the way the fuel line was sitting, sediments would build up and get clogged in the line, causing it to have a problem getting fuel under heavy acceleration.
