61 Lesabre I replaced the rears years ago and they worked great, did flash faster but all good. Today I replaced the fronts as the old bulbs were stupidly dim. Now the rears come on and stay on (no flashing) when I use the turn signal, and the fronts don't come on at all. I know the bulbs are good as when I turn on the park lights they shone bright. I have a thermal flasher so will pick up an electronic one tomorrow. I have checked all wiring and getting about 7 volts to the lamp socket when turn signal engaged (I have tested that with a DMM with the bulb removed). I did try an inline 1 ohm resistor but that made no difference. Is there anything I am missing other than I need to lose the thermal flasher and go an electronic one?
Go electronic, should solve your problems. How did you ever make out with the oil/temp. lights??? Tom T.
Tom. Got a second dash as it turned out it was the circuit board on the temp lights. Oil works now. But the second one which obviously is second hand also had damage. So I just bought a full set of Dakota digital gauges which will be my next project. But will need to build a housing as the 61s have the mirror dash
Chris, Those flimsy circuit boards CAN be repaired. The problems arise when people are testing & putting power to the wrong place. Originally the ground was through the ignition switch. Tom T.
Yep I know but I do like a digital dash, have one in my Camaro. On the turn signals. I put an electronic flasher in. Rears flash but are dimmer than usual. Fronts don't even come on nor flash at all...they do come on in park. They are 1034 style lamps, but I did not check voltage...only 7 volts to the lamp casing so may need to get some that work at 7 volts
With LED, the polarity is important. Can you test the bulb to see if they are wired properly and the sockets have + and - in the proper spots?
