Hey guys... Weird problem... I'm fairly electrical savvy but having a weird problem I'm hoping someone else has run into.
The farm I work for has a 2001 3500 5 speed service truck. A few months ago it started having PCM problems so I installed an external voltage regulator. Echlin/NAPA VR38.
It was working good until about 3 weeks ago. It started to show 18v on the dash, it's actually getting at high as 15.5v on a meter at the batteries, but it's high enough to set a CEL and blow headlights. We swapped regulators, exact same problem. I jumped a clean battery 12v to the regulator sense terminal, no change. Ground is good.
Any thoughts? Truck is out of service and there's 1800 acres left to harvest...
