I finally put a battery in my 914 LS1 conversion today. Nothing blew up, nothing caught fire... a good start I think. I have the JWest fuse panel and as a precaution, I also installed a small fuse block at the battery.
Here's my dilemma. I can turn on the parking lights, but turning on the headlights immediately pops a fuse at the battery (I've gone as high as a 30 amp fuse). None of the fuses in the JWest panel have blown. I checked the fuse panel, headlight switch, and headlight relay. All seem to be wired correctly with no visible shorts. I currently have H4 headlights installed… for the time being the wiring is stock. A friend suggested the H4's are drawing too much current, so I tried again with the bulbs unplugged… same result. I'm stumped. Where do I look next? |

dadaDaveed,
Since you have a conversion, it is going to be harder to help you as the prints we have no longer represent a true wiring diagram for your car. I would look back at what you have done with the wiring to make the conversion.. Since you removed the wire from the battery to the starter and the problem went away, there is an issue ( I bet) with the wiring to the alternator. Take that wire off where it connects to the starter larger post and hook the starter to battery wire back up. If it no longer blows fuses, you have a wiring issue that has something to do with the wiring between the alternator and the wiring in the dash. Go back over what you have done to hook up that Chevy alternator to the wiring. Aren't you glad you put that fuse block in? (IMG:style_emoticons/default/smile.gif) One more piece of advice, when you hook the battery up, leave one post hand tight so it will be very easy to remove in case something bad happens. Much easier to control an electrical fire if you can remove the power quickly. This holds true anytime you have been doing electrical work and always disconnect the battery when working on the electrical system. Removing the negative battery cable is all that is necessary.
