tach and headlight problem

[tjhummer]

Hi all, I have been lurking for days looking over all the posts regarding headlight and tach problems. My headlight and tach quit working at the same time, but for only a few seconds. (This is a problem at night on curves.) I have replaced the old fuse holders and fuses, checked the alternator connectors (clean and dielectric grease) behind the fuse panel, checked for charge voltage (14.6v), still have problem. What I am looking for now is where the connections are where the headlight relay and tach signal tap into the alternator winding. I don't want to disassemble more than I have to getting at the right spot.

Under the gas tank is the regulator.Check connectors and grounds.I f you have tach and lights sometimes it is probably a
connection of some kind.If no tach or lights at all it is probably the regulator.

I have headlight and tach most of the time. They just cut out for a couple of seconds here and there. No problem during the day, but at night out on winding roads, it's kind of hairy. Thanks for the reply.

Sounds like the reserve lighting device has a loose connection or is about to take a poop.
This part is a square black box located under the fuel tank.
