My brother had a guy install a Holley Sniper EFI. Ran OK for a bit, but it shuts off at random because of a drop in voltage. I’ve read they’re super sensitive, and will shut off if it drops below 12v. At the moment it’s powered full time from the battery with the startup wire (pink) tied into the ignition as the directions call for. Problem is, the voltage drops on the ignition wire on startup thus getting a no start. It has a 140 amp alternator, the battery is good, everything is charging. I know a handful of you have installed these. What 12v source are you hooked to that doesn’t drop on startup? I suggested straight to the battery with a toggle switch and relay, but he wants to keep it clean on the dash. Thanks in advance
