Original or Aftermarket Tach - The 1947 - Present Chevrolet & GMC Truck Message Board Network

70StepsideC10 · 09-17-2020, 12:47 PM

I am starting to put together a tach cluster for my truck. I have found the tins for a good price, and the guy also has an original tach for sale. I asked if it worked and he said it can be tested when I am there to pick up the tins. He is asking $90 CAD for the OE tach. That might sound like a lot to the Americans on the board, but for comparison an aftermarket tach locally is $180, and if I was to order one from the US it would be around $150-$160 with shipping and exchange rate. Saving money is always good, but I would hate to buy the OE tach and have it fail. So I thought I would ask the guys out there that have tachs, either OE or aftermarket, what they thought. Do tachs go bad often, or are they fairly robust? Or should I spring for the aftermarket one and some piece of mind? Thanks in advance.

I just had the one in the ramp truck go out and I bought it new back this winter. I'm waiting until I get back home to call about it and see if they will do anything on it.
I posted this back when I bought the tach after finding his site on e bay.a

Thanks for sharing that Andy. I didn't know you could get replacement tach circuit boards, that is a great option for failed OE tachs. Good luck with getting a replacement for your failed tach, hopefully they can send you a new one.

So Andy. Does this new circuit board work?
I have my old Factory Tach that I’d like to fix for a future project, but if this won’t work then I won’t order one.
