electrical is baffling me-help!!

Slant6'4 speed- Im thinking the same- bad ground. The fusebox was getting real high volts and hot as h#ll. The headlights would work till I either hit a bump or -now that I think about it- curves and hard turns. $40 in headlights later....

Anyone know of a kit to make the headlights into halogens like the 9004's or H4 bulbs? I did this to my Porsche 944 and love it. It just runs battery power to 2 relays then out to bulbs. That way you dont use old factory wiring for the extra juice. I saw a wire set from year one?? but they want over $100. Made a big difference on the '84 944 I have. Unless someone has a diff suggestion? Oh- been running these on the other car for 5 years now with no prob and its my daily driver.
