Well I am just about out of ideas.
Connecting the positive side jumper made no difference, so I am going to rule out resistance as the cause for the charging delay. I have tried a jumper on the ground (alt to bat) that didn't help.
I saw on Fastlane there is a glow plug relay that has extended heat time. That may explain the delay before seeing full charge voltage but I think mine is the stock Bosch unit. Anyway, when the relay cycles off it is clearly visible on the Fluke but there is still a delay after that before it begins showing full output. I wish I knew what to check on the relay so I could rule it out.
This one has really got me stumped boys.
