I think it;s those two broken head-bolts stuck in your block!

:lol:

ok... just kidding.

Grab a wiring diagram for your car (if you do a search on this forum, you'll find some done by Brad Artigue that everyone here seems to love.
You will note that if you're just hot-wiring with two wires, then you're not getting everything energized.
get that wiring diagram and trace it out.

the other option is to do like the guy in the other thread about electrical issues did. :wink:

Not sure what year your car is. The diagrams for an 81 show:
There are 2 wires on the alternator output. The larger goes to the starter. The smaller connects to fuse 10 to feed that fuse and fuse 9. These fuses are internally jumped in the fuse panel. The hot side of Fuse 9 (black wire) feeds terminal 30/1 of the ignition switch. When the ignition switch is in the run or start positions terminal 30/1 connects to terminal 15/54 to feed the ignition, Fuse 1, the battery charge indicator, and fuel injection. I would check the push on connections on the top of the fuses first. Then check C31 the connector for the ignition switch for loose or over heated connections. The above mentioned connections are not Fuse protected so I don't think you will find a fuse as the problem.
If you have a trouble light it would make it easier to find problem

spider 2081, thank you, thank you ,thank you, the second lead off the alternator that is not the starter lead had literally fallen out of the connector at the alternator explains the flickering of everything as it would have been making momentary contact . repaired connector and everything came back to life ! :) so once agian thank you for your help muchly appreciated !!!!!!!!!!!!
