Ok here's the deal. Turn signals and hazard lights all work. I just replaced the pea lights in the tach. I have no voltage to the socket, When I checked the wire it goes to ground. Looking for someone with more undamaged brain cells for trouble shooting ideas.

Here's a simplified diagram of how the flasher circuit looks when the flasher is on for a right turnsignal.
The flasher output 49a connects the right side bulbs to the battery and thus they light up. Flasher output K also turns on and connects the center connection of the tach indicator bulbs to the battery. Notice the right side indicator is connected to the left outside bulbs and the right side indicator is connected to the right outside bulbs. When working correctly, the right side indicator current goes from the battery, through output K, through the indicator, and further through the left side exterior bulbs. Since standard bulbs need a lot of current to light up (>1A), the small current of the right side indicator does not light up the left exterior lights. Attached image(s) |
