Spot light

rasbury

I have the std rinker installed remote control light. When we first purchased, the light did not work, assumed it was the bulb. I replaced it, that was the problem and it worked fine.  Hardly ever used it but always exercised it at home or overnight. The bulb is again not working. I checked both fuses at the control and they look fine- I should be able to pull the fuse and probe that for power correct? I don't know that my multimeter can get that derp tovtest- i don't think anyway to test from the backside. I really thought there was a problem with that control head plus it looked like crap so I replaced it...also, before I replaced that, the up and down control was working but left to right was not- new control head did not fix anything. Looks better! So, assuming I have power at the control head for the light, how do I verify the bulb is bad- they are not cheap. The left to right, what am I looking for there?

Use your meter to test the bulb.

As a continuity test?

Yes, if I recall there are 2 filaments in it like a home 3 brightness light bulb. Measure each contact pin to the metal body. Resistance would be around the result of 144/wattage so if one filament is 100W, the resistance would be about 1.44 ohms.

Thanks  @Ian. I can follow goid instructions even though I have very little idea of what I'm doing. I should also be able to probe the fuse holder to determine power? How about ar the light head itself?

You should see voltage on one side - the incoming side - with the fuses out.  If it’s the same as mine from factory there’s 2 fuses, one for light and one for motor. If you have power on the incoming and the fuses are good then you could then carefully probe the bulb holder to see if you get voltage there, again there should be 2 contacts for the 2 filaments.
