Re: 67-72 Tac...
FYI - Just so everyone knows, the board Andy purchased is for OEM stock Tachometers, not the aftermarket tachometers. The circuit boards are totally different.
I ordered the board, and when it arrived I realized I had a reproduction tach, not OEM. I contacted Cajun Tach Shop, and Greg was very helpful. There is good news....he just came out with a replacement board for the reproduction tachs. The reproduction tachs have had issues over the years of burning out after a few months. The reason is the heat on a particular resistor. You can replace the resistor, but it will eventually overheat again, and burn out. Bad design. Greg's has designed his replacement board for the reproduction tachs to fix this issue. Anyway, just wanted to get that out there for those with reproduction tachs. If you have a reproduction tach be sure to let him know. Here is a pic of the reproduction tach board. If you have this board you have a reproduction tach. |

Re: 67-72 Tac...
Just one guy’s experience but my reproduction tach has lasted over 5 years already. No burnt resistor. Can’t recall where I got it but it was one of the big vendors, I’m sure.

Re: 67-72 Tac...
Just an update on the new circuit board for the reproduction tachometers.
Greg at Cajun Tach Shop did a great job on installing and calibrating his new replacement circuit board for the reproduction tach that I had. The tach reading is crisp and steady. Cannot wait to get out there and cruise. Thanks Greg! |

Re: 67-72 Tac...
Just wanted to reiterate this. Greg does not recommend buying his boards for the reproduction tachs. You should send him your repro tach so he can rebuild it and calibrate it to the new board. There are too many variants out there for him to make a 'standard' board.
