Sled: 1977 Scorpion Sting, 2000 ZL 500
I own a 1998 AC Pantera 580 EFI that was second or third hand when I bought it. The tach never worked for the 2nd owner so I decided to investigate. My shop manual for this sled shows only a yellow and a brown wire connected to the tach. The manual also states that any yellow coded wire will work for the tach signal. The tach on my sled, however, has 1 Black, 1 Yellow, and 1 Red wire screwed directly into the back of this tach? The model number for the tach is 0620-200. Does anyone know what the red lead is for? I am using an "official" Arctic Cat Service Manual specifically written for the 1998 Pantera 580 EFI and the EXT 580 EFI DLX. The wiring diagrams (color codes) in the manual do not match my sled exactly. My sled was built in Sep 97 - is it possible there was a wiring change in late production?
The main wiring harness color codes exactly match the tach receptacle color codes so this appears to be the correct tach. I have tested a known good 0620-200 tach on this sled, but even this one does not function. Does anyone have any troubleshooting tips? If I can't trust my service manual I am lost!
Bummed Out in New York - I just can't ride without a tach!
Thanks in advance
