Radiator Fans current draw messing with Megasquirt
i have Mesgasquirt running on my Alfetta quite well.
However when the coolant heats up and the radiator fans switch on, the current drawn causes the engine to loose revs and go lean while the fans are on.
Everything goes back to normal when the fans switch off.
I had the alternator re-wired from 60+ to 85 amps but it made no difference.
The Auto Electrician said the wiring was all ok and that he felt the alternator wasn't turning fast enough at idle, so I put the smallest Alternator pulley i could get, but still no good.
I don't know how much current the two fans draw, but I was wondering if anyone else has similar issues and what can be done to rectify it.
I'd rather push my Alfa than drive anything else.
