Hello,
I think I'm chasing a ground problem on my 83 Interstate.
I puchased nice high power LED's for the brakes and signals. These are actually nice and bright and work great on a test bench. They won't work properly in the sockets. The brake lights work but the running lights don't. When tracing the problem I find that I have .02v on the brake circuit and blinker circuits when the brakes and blinkers are off. This seems to be enough for the internal circuitry of the 1157 LED bulbs to switch over to stop mode and dissable the running light mode. When I disconnect the sockets from the wiring harness and manually feed them the bulbs work just fine.
It looks like I am somehow feeding a little current into the brake circuit and blinker circuits but I can't find where. When testing on the front blinkers socket I removed all the fuses but the running lights fuse, disconnected the blinker relay, the signal stop module, removed all the bulbs except for the intrument bulbs, and I still have .02v on the brake circuit and blinker circuit.
I've just cleaned the main grounds connection at the battery to frame/engine mount. There are two other grounds connections shown, one in the fairing with all the other unused connectors and one by the fuse block. I can't find either of them.
Could someone explain to me where these other ground connections are or suggest what else I should be looking for?
Thanks
Jorg
