Turn Signal dash problem Options

[Sea Dragon 914]

I have a 73 914 that has a curious problem in that whether the left or right turn signal is turned on, both lights turn on my dashboard blink dimly instead of one side or the other like my other 73 914.

What could cause this problem?

Thanks in advance for the help.

This has come up before. My early build '74 (build date 8/73) has two bulbs, but both flash together whenever a turn signal is used.

There was a rumor that replacing the turn signal relay with one from a VW bus would solve the issue... In fact, I think I vaguely remember ordering a bus relay for my parts stash, but I've never installed it.

Except in direct sunlight, it's usually easy to see the edge of the front turn signal lens flashing to confirm I've flicked the right correct one.

VWs, except for 1970 or so and older, use a 3 prong relay. Doesn't have to be a bus, they use the same one for all of 'em up to at least the late '80s or early '90s. IIRC, 3 pin relays don't work in place of 4 pin relays. If they worked, we'd all be running 10 dollar VW turn signal relays ..................................
