My '88 RRC has been running pretty well since tinkering over the past few months, and much thanks to all here. Two issues I'm still encountering that confuse me are that both my Tach and Temp gauges are inoperative. The rest of the gauge cluster works fine.
I thought these issues were related to an alternator change and failed internal voltage regulator. I was using an Ultima brand alternator (inexpensive) so I warrantied it out for another, still no Tach or Temp. Each time I replaced the alternator, I reused the capacitor looking things off the previous alternators that have wires connecting to the back of the alternator (one of which I thought was to control the Tach). I recently switched over to the Bosch alternator and switched out one of the capacitor things, but still no Tach or Temp.
Any ideas on what I can do to resolve this issue?
If it is those capacitor things, where do I get the correct new ones? I didn't see them on AB and the local parts stores don't seem to know. They just tell me I have to reuse the old ones. The new one I got came with one of the alternator replacements but not two.
Also, I'm thinking about installing an auxiliary temp gauge. Any recommendations?
Thanks in advance
