unique tach issue
hi; I have a 1980 vette that i have installed a 2012 ZZ4 crate engine and the tach filter stopped working after the car was driven hard, i have subsequently burned up another filter and 2 boards. the second filter shorted to ground and overheated my module thus no spark, when unplugged from the tach output the car started and ran fine.
i then ran direct which worked fine for a while and eventually stopped working
I think that this new distributer 2012 has too high current
perhaps a simple ballast resistor in line with a new filter or possibly building a more robust filter
any advice would be greatly appreciated
thanks

the distributer is from GM that came with the ZZ4 turnkey package.
last time I installed the new filter and board all was well at start up then after a bit of hard acceleration the filter failed.
I wish I could learn why before I replace the filter and board once again

Bypass the filter and see if the board is still working. If it's our board, it's fused and an easy fix... 14.00 plus shipping.
