I read that disconnecting the wire on the alternator overnight and check battery level in the morning. But I did not say which battery wire. I Believe they meant the Large Red Output Wire. Usually there is another plastic connector with 2 more wires. I can't seem to access the rear of the alternator. I'll take the cowl cover off inside the van. Supposedly It may have a bad diode inside the alternator. My alternator charges, but I've been disconnecting my battery cable every time when I'm done using the van. A mechanic told me to turn on headlights, wipers, heater fan, & step on the brake lights while watch the if the voltage gauge drops from 14 volts. It did not drop. I was reading on You Tube this morning ADP Training/ Build your own test equipment and the narrator mentioned that Body Control Modules, ABS, SRS, and
other sub system modules can cause parasitic drain. And ADP shows how you can build a diagnostic tool from electronic components called a Fuse Voltage Drop Short Identifier together with a Voltage to Amperage chart they've developed in 2012. They say to try using a DMM first because their meter is sensitive. And to Test across System fuses
while the fuses are installed in the vehicle. - I know its sounds like I answered my own question here but I always need a game plan on where to start poking around. Electricity was never my forte I graduated Electrical Construction and Maintenance at my local community college. Let me know if you have any new angles. Thank you ! : )
