Sorry I meant to say--it's for radio noise suppression. It's likely not needed for the new solid state limiter. The old limiter worked just like a flasher --pulsing the power on /off and generated spikes which would have made "ticks" in the AM radio
Thanks, I thought it was for the radio but not sure. I have the new limiter, new cluster sockets, lamps and a new headlight switch so hoping to get the instrument cluster working. I will try grounding the sending unit lead right at gauge to see if gauge is good. I will also clean up all gauge connections. If i find the gauge is bad is there something I can do to it or replacement the only option?
