Back at the Cuda again!!!
A couple of things I has seen mentioned on the Holley Sniper forum was low voltage.
1. Low voltage on the +12V Key on feed to the sniper when cranking. Apparently anything below 11 volts causes problems on starting. I connected the IGN1 feed to the sniper feed and then cranked the engine. Sure enough, the voltage was below 11V. (The IGN1 also connects to the voltage regulator which pulls the voltage down)
I made a wiring mod to add a relay to ensure I had a >12V supply to the sniper as well as the voltage regulator.
2. The forum also mentioned low voltage conditions when idling with headlights and heater on etc. The stock alternator does not put out sufficient voltage under high load and idle speeds. I've now swapped out the original alternator for a Powermaster 7018.
Powermaster 7018 Powermaster Retro Alternators | Summit Racing Hopefully that will solve this problem.
