Im sure this has been asked before but I did a search and couldn’t find the info I needed. Closest thread was about resistance wires.
After some restoration work, I switched to a Pertronix igniter distributor. I think that caused the factory tach to quit working.
Just installed the MSD 6al .
I knew I’d need a tach adapter so I did some research and concluded I needed the 8910.
Hooked up the 8910 and went back to a no-start situation. Unhooked it, and it started.
Called MSD and the guy told me to remove the ballast resistor/resistance wire to the tach.
Before I do that, I want to check with you guys to make sure it’s safe. I don’t want to remove that wire and cause a fire or fry something.
If I should bypass the factory resistance wire, please explain the reason why it won’t be unsafe to do so. My guess is the 8910 compensates for that, but not positive so want to make sure.
