Re: Tach flickers
Revive an old thread, I am having the same issue, I replaced the Msd 8360 distributor and put the stock one with pertronix back in, it went away and I thought I was good, went to the cruise last night and all was good until I had my left turn signal on and noticed it bouncing, turn signal off and it started acting up again.
I built one of the tach filters, no change, checked every ground I could find, tightened up the headlight switch, nothing!
My next though is seeing that it worked cold and started acting up at the end, maybe it is the voltage regulator? I already have the vr715 electronic one in there, my next step is to replace it, itís only $22
Any ideas would be helpful, btw, I did replace the tach with a brand new one, no luck
