I'm having trouble with my turn signals. I've got a '54 Chev. 2-door sedan that's converted to 12v. When I changed from 6 to 12v, I changed all of my bulbs and my flasher. The turn signals worked fine for a few years.
My problem is, I keep blowing the in-line fuse in the turn signal circuit. When I changed the fuse yesterday, I noticed the wire coming out of the fuse holder had fallen out. So, I soldered the wire back in and replaces the fuse (I'm using a 20Amp fuse). Now, when I turn on the ignition, both turn arrows in the dash light up. When I flip the lever (right or left) both arrows flash. This doesn't make all the turn signals on the exterior flash, though. And, when they flash (right or left) they start out at the normal tempo for the first couple flashes, then the tempo increases.
I've got a basic understanding of automotive wiring, but this one I haven't figured out. When your flashers blink fast, that usually means there's increased resistance in the circuit causing the element in the flasher to heat up faster. And I thought if I have a bad ground, that would be more resistance, but why would both dash arows blink? Is it possible that if one ground is bad, it could backfeed thru the other indicator to find a ground on the other leg of the circuit? That would add another element to the circuit, increasing the resistance. But wouldn't that only be the case when turning to one direction?
I'm going to go check all of my grounds in the circuit, and try putting my spare flasher in. But any help you could give me would be greatly appreciated.
