<x-flowed>I have a 70 squareback, and it has a short somewhere that popped up the other day, and is preventing me from driving the car. It showed itself as i was driving home from work on a day when i had to drive to work in a bad rainstorm. It does get a bit of water into the cabin when driven in bad rain, and this time i found a bit of water in the battery compartment. The short didn't go away when all the water evaporated though, so it may be coincidental.
First off, the mods to the car. EFI was pulled for baby Webers prior to my owning the car unfortunately. The shop that did the conversion clearly had no clue what they were doing, as shown by the use of the stock fuel pump with no fuel pressure regulator, pumping 15 psi into carbs designed for 3. I'm sure they didn't bother to remove or disconnect the EFI wiring, but that'll be the first thing I check when I get out to work on the car. Also, the ignition cylinder had an issue with the previous owner, so he removed the starter wires and wired them into a momentary pushbutton switch.
OK, now the problem. When the key is put in the run position, the car is fine, I hear the fuel pump going, and all lights and accessories get power. When the starter button is depressed, the car immediately loses ALL power. No fuses blow in the glovebox, but everything dies, and stays dead, until the battery is disconnected and reconnected. Is there a circuit breaker I don't see in the wiring harness that is tripping? I'm thinking that the short is occuring in either the starter/solenoid, the generator/regulator or the wiring of those to the battery, as all accessories seem to work fine. Any suggestions of what to check? Anybody experience anything like this?
Thanks to all for their help,
