RKL PC4 issues please help

Curve · 12/09/2011, 07:23 AM

Okay I have a RKL on my 210 and its been in use for 2 years or so. Well every now and then it will tell the lights to turn off but they wont. They stick on. I can usually bump the pc4 and they will turn right off. Well this morning they were stuck on and no matter how hard I bump the pc4 they would not turn off. This only happens on ch4. Any insite on this or do I just need to replace my pc4. If so the pc4 cost as much as the whole controller almost.

Any suggestions on this??

Open the pc4. Order a replacement (same) relay off digikey and solder it onto the board.

No biggie. Probably a few bucks.
