I'm trying to be of some assistance to the guy in town who is getting his -6 put back together and troubleshooting the myriad of little issues after a restoration. We already figured out that his speedo drive got swapped with a 911 unit at some point so he has the correct one on the way.
The issue at hand is tachometer isn't working. All gauges were rebuilt. I can't remember who he said did them but I recognized the name as a reputable place. The tach has the purple and black wire hooked up to it, but there does not seem to be a purple and black wire back at the coil. Just the main wire to the distributor, and one wire on each terminal. Any ideas of what to look for and check? Are we missing something obvious? |

I stopped by his house on the way home from work to borrow his 700 tech tips book, we poked around a bit more on the -6 while I was there. The tach adapter is in place on the relay board. I forgot to ask the year and if he's got CDI in place currently or not.
I think next step will be trace the tach wire and check resistance make sure that side of things is good. Is the routing for that wire the same as on a -4? |
