Need some help: Tachometer displays four times 3.200k @ 800RPM
Hello FABO Members!
I need your help. I wanted a tachometer for my 1965 Barracuda Commando V8 and was searching for different types. When I found these pictures, the decision was made...
The Golden Commando Goldfish ran with the Sun Pro Tach in 1965. So I bought the Repro Sun Pro Tach. Everything was fine (set the switch to 8Cylinder), but when i tested the Tach it displayd way too much. Fourtimes too much. 3.200-3.600 (800-900RPM) when cold... So i switched the hole Cylinder Set Up at the back of the Tach (1-2-4-6-8-10) but it got only worse.
Last year I changed the original dual point distributor to a matching pertronix electronic ignition - thanks to the FABO
Working on electronic ignition conversion for HP273 dual point distributors
Maybe this causes the problem? I got a tip that there is an adapter (by SunPro), which could help and solve the problem...
But this Adapter is sold out everywhere:BangHead:
I was at a local Tachometer specialist (VDO Instruments and Gauges), but they couldn't help me either with my problem...:(
So at this point I do not know what I can do to fix the problem...
My Car
1965 Plymouth Barracuda Commando V8
273 4bbl
dual point distributor -> now -> Pertronix electronic ignition.
Maybe someone has an idea.
Thank you in advance!!!
