Patcon Posted July 26, 2017 Share #1 Posted July 26, 2017 @SteveJ We are having a new turn signal problem. If the right turn signal is on it flashes properly with the brake lights on or off. If the left signal is on all the lights flash like the hazards are on and if you step on the brake they become solid (no flashing). anyone please feel free to comment...

SteveJ Posted July 26, 2017 Share #2 Posted July 26, 2017 Start with the left rear. Remove the bulbs and inspect the sockets. Look for a cracked insulator on sockets that take an 1157 bulb. Look to see if an 1156 bulb was used in a 1157 style base. (Single filament bulb in a dual filament socket) Test with the bulbs out. See if the problem remains. Also post that wiring diagram for the 510 again. Link to comment Share on other sites More sharing options...
SteveJ Posted July 26, 2017 Share #3 Posted July 26, 2017 I found the wiring diagram you posted before. The 510 doesn't have the same potential for cross connections as the 240Z. The turn signal switch on the 510 does not affect the brake light circuit. Also the turn signals and brake lights only share a ground. They are in different sockets. The tail light housing serves as the grounding point for the bulb sockets. Link to comment Share on other sites More sharing options...
NVZEE Posted July 26, 2017 Share #4 Posted July 26, 2017 (edited) Here's a color diagram from 510maester Kelvin Dietz that doesn't solve the immediate problem but is a good thing to have handy: https://drive.google.com/file/d/0ByCvxnHNk90SSmpJOXMxekR2cnc/view Edited July 26, 2017 by NVZEE Link to comment Share on other sites More sharing options...

Patcon Posted July 30, 2017 Author Share #6 Posted July 30, 2017 Well this is where we're at: With everything plugged in, in left turn all the exterior lights blink but only the left turn on the dash blinks. We unplugged the front left turn signal, both rear brakes lights still flash when the stalk is on left turn, but the left turn still blinks properly With the front signal unplugged and the left rear bulbs removed the right turn still blinks in the left turn position. If the brake is pressed in any of these positions the brakes lights quit blinking and become solid Link to comment Share on other sites More sharing options...

SteveJ Posted August 3, 2017 Share #8 Posted August 3, 2017 I'm thinking there might be a ground issue somewhere here. There aren't any dual filament bulbs for the turn signals, are there? Link to comment Share on other sites More sharing options...

There aren't any dual filament bulbs for the turn signals, are there? We took the bulbs out on the drivers side entirely. So that should eliminate an issue of the wrong bulb in the wrong socket. There was a duel filament bulb in the taillight. You know, we had the signals sorted after you came up the last time and now they don't work. My assumptions were: bad signal switch, bad hazard switch or bad grounds. I had thought I would unplug the signal switch and jumper the left turn signal and see if works correctly to try to narrow down the problem...Any issue with that?

SteveJ Posted August 4, 2017 Share #10 Posted August 4, 2017 Yes, you should be able to jumper the contacts at the connector. I'll try to see if I have any video or photos of when I cleaned the switch. Link to comment Share on other sites More sharing options...
Patcon Posted December 3, 2017 Author Share #11 Posted December 3, 2017 We solved this. I bought a refurbished switch off of Ebay and that fixed this issue Link to comment Share on other sites More sharing options...
Patcon Posted January 7, 2018 Author Share #12 Posted January 7, 2018 Guess what??! The signals don't work again. Nothing flashes... I don't know yet if anything lights up... Link to comment Share on other sites More sharing options...
