Tach at 3,000 rpm at idle
We have just installed a Holley Terminator EFI set up with Holley Hyperspark distributor, ignition coil and CD ignition box on SBC in my C10. The tach (5,000 rpm add on restoration one in dash) is now showing 3,000 rpm when idling, read out on Holley display is correct.
Anyone encountered this problem? Where to look? thanks |
