Ok, I'll try and make this short and sweet. '75 850t flasher relay doesn't want to flash. Can't get signal lights on period. Hooked up all 4 turn signals I have and none of them came on (unless all 4 bulbs happen to be bad, I didn't take the time to take 4 lenses off). I hear the flasher relay itself click/actuate when I turn the key so I'm assuming I have that wired correctly. I have continuity on both turn signal wires front to back, but can't get a volt reading on them when I have power running. Not sure if I'm supposed to or not, but I figure it's worth mentioning. I know hardly anything about relays but 2 of the 3 terminals have continuity, the one on I believe the left doesn't want to read.
The only thing I can think is that its the turn signal switch itself or I do in fact have 4 ruined bulbs. Would the rear flasher unit affect any of this? Only just now thought of that >.<
