Weird electrical problem.... Any ideas????
Weird electrical problem.... Any ideas????
Started yesterday morning was going about 75 down the highway, then all of a sudden ignition system just stopped like I had turned the key. The weird thing is that my tach also bottomed out and went to zero, the car was still in gear so there for should of still been turning at around 3200rpm. Pulled over and then restarted after checking engine bay for loose wires, blown fuses, and relays. Then last night it did the same exact thing, this time it happened when I pushed in the clutch on the highway, tach bottomed out like before. But when I pulled to the side of the road this time there were blue sparks coming off my exhaust manifold when I lit my lighter check the engine bay. But the only time there were sparks was when I hit the lighter. ANY IDEAS AT ALL????
my car did that, check your battery wires and any wire of that nature, my car doesnt even shut off with the key, i have to have a kill switch with kill it becase several things stay on when its shut off. i dont really know if i helped you in any way, but i guess it might be a little reasuring that my car is plaged with electrical problems. so your not the only one,. thats why im getting another one.
i know exactly what it is. your engine harness is shorting out on the head. give me a pic and ill show you exactly where its at. im not the only 240 thats had this problem. i tried to source the problem for a week. well, see if you can find it by me describing it. its right on the right front corner of the head where the harness meets it. the harness over times just rubs against it and eventually through the wires. this is why your manifold is giving you sparks. if your ignition fusbile link fuse blown? most likely. just pull the harness back and take a look. let us know what you find...
So I took apart every wiring harness in the engine bay. Opened up all the condouit and looked at all the wires, I couldn't find a single wire that has missing insulation or even cracked insulation. So now I am back to before with no ideas. BTW I now have ran a ground wire from the exhaust manifold to the frame to get rid of the "electrically charged" exhaust manifold.
Problem fixed, the previous owner put an ignition kill switch on the car, the stupid thing was that it was hidden behind the starter up against the block. Yanked this out spliced and soldered everything back together and now we are all good. While I had the electronics torn apart I took out the clutch fan and hooked the A/C fan up to my ignition so now I dont have to turn that clutch fan and also removed the rest of the A/C junk so my radiator gets all of the air coming through the grill. Thanks for the ideas though guys.

screw using aftermarket fans, check out what i did....http://honda-tech.com/zerothread?id=802477
I just ran zipties around the fan bracket and through the fins on the radiator, sounds ghetto but it is the way that my old permacool fan was mounted so I went with it. Just run a zip tie through one side then let it run over about an inch of the fins on the engine side then stick it back through. I just did this three times and used a bolt and a stock mounting point on the bottom. And yes it pushes enough air through if you remove all the A/C junk blocking the airflow.
