erniestr8mingin Posted November 27, 2017 Report Share Posted November 27, 2017 So my dimmer in my '75 620 has been fried due to a ground issue, and I am looking for alternatives. I can't seem to find another. Will another dimmer from another Datsun with a 2-pin dimmer work? If anyone replying to this thread has a spare that would be willing to let go of, that would be great as well. Thanks!! Quote Link to comment
MikeRL411 Posted November 27, 2017 Report Share Posted November 27, 2017 I find that once I set the dimmer on a new car I never readjust it. Quote Link to comment
datzenmike Posted November 27, 2017 Report Share Posted November 27, 2017 All (I think) are three wire. The same dimmer is used on the '70s cars also. Earlier are rheostats, around mid '70s they changed to a much slimmer solid state that doesn't heat up. Quote Link to comment
erniestr8mingin Posted November 28, 2017 Author Report Share Posted November 28, 2017 On this ad below for a 75-78 280z has two wires, just want to make sure if this would be compatible to use in my 620, and that this one on eBay isn't a solid state one. Thanks for the reply datzenmike! https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F112623759094 Quote Link to comment
datzenmike Posted November 28, 2017 Report Share Posted November 28, 2017 Yeah, if only $15 get it. Ahh I see that the 620 used a 2 wire until '78 when it went to a 3 wire solid state. Don't know if the two can be used for the same thing, but I expect so with some wiring. The two wire just add resistance (which will have to dissipate some lost heat) the solid state is more compact and transistorized. 3 wires. One is ground. One goes to power. One goes to all lamps on the ground side.The other side of all lamps go to power. 1 Quote Link to comment
