I have to hand it to you Web....nice write up...and a great project. This old guy has had to play catch up for years on all this computer, sensor, control crap...but, it is interesting. And I am learning. My big old cummins engine was losing power, slowly, and with 440K miles on her, I chalked it up to needing injectors or something...but, the other day, the altinator started to go, and I had noticed for sometime, the voltage was low, but that happens. Well, no it doesn't...in the old engines, not a problem, but in a computor, sensor controlled world, voltage is important. I found once the new altinator was installed and I had my voltage back, so was the power...so yes, I am learning....lol
