Tach problem
I installed my Auto Gauge tach tonight. And its not working. The green wire is in the MSD 6al Tach Output slot, Red is in fuse #11(radio), Black grounded, and White into fuse #13 (Illumination). The needle just sits on the shift point and won't move. Does this sound like I need a tach adapter or need to do some rewiring?

Re: Tach problem
Running off the msd you shouldnt need a adapter. I would check ground and be sure i have ground, most of the stuff in and around the dash is plastic, may be nessary to just run a temp. wire from ground and hot battery just for checking purpurse. does the needle move any at all? Does key on and key off make any differnce? May have a bad tach. Hope this helps

Re: Tach problem
I have the ground ran through my firewall onto the fenderwell. Once cranked I can turn the needle with the shift set knob, but it won't go past 1k rpms, it stops there

Re: Tach problem
It is getting power from the key on, b/c once key is on(not cranked) it will move to the previous shift point. Once cranked it drops to 0 then shoots to 5k(shift light point) and sit there. Which makes me think either need adapter or broken tach

Re: Tach problem
Hook the tach signal wire to the neg side of the coil that way you know you have a signal. The tach output on the msd 6al might be burntup.

Re: Tach problem
Yea, I ran a voltometer(sp?) to the tach output and was getting negative reading. And you can't run the tach to negative coil with MSD b/c it will fry it up and void warranty.
