Rod, as someone posted on my similar question, you probably have more than one leakage path. The fact the voltage changed means you eliminated one or more in that tub, but that there are still others. If the TEVan has a floating ground, you should read zero from everywhere on the high voltage system to chassis ground. The high overall voltage is scary. I'd look for a more obvious problem, like worn insulation and contact with the chassis somewhere, or failure in some component like a DC/DC or something. Could there be any electrical leakage in the watering system?
IIRC, The typical troubleshhoting procedure is to leave the connections alone, and measure voltage to ground at each battery terminal, working from pack positive or negative to the other end. If you have just one path to ground, then you will have found it when you read positive on one side of it, zero at it, and negative on the other. When you have two or more paths, it gets more interesting. -----Original Message----- From: Rod Hower [mailto:[EMAIL PROTECTED]] Sent: Monday, September 23, 2002 9:59 PM To: [EMAIL PROTECTED] Subject: ground fault leakage I spent several hours trying to figure out why my TEVan charger kept tripping, I thought it was due to ground fault leakage. The TEVan has 6 battery tubs, 4 with 6 batteries and 2 with 3 batteries. All are interconnected with Radsox connectors for quick disconnect. Using my multimeter and a 10k ohm resistor I measured the following voltages (AKA leakage) This was measuring between Chassis and battery positive and negative after disconnecting the Radsox connectors between battery tubs positive negative overall 110vdc -68 Tub1 25Vdc -46 tub2 71 -55 tub3 86 -50 tub4 80 -27 tub5 73 -5 So it appears from the measurements that there was big time leakage in tub2. That is the leakage from battery positive to increased from 25vdc to 71vdc. So I dropped the tub and cleaned it quite well. After reconnecting the leakage on the positive pack side was higher! overall 134vdc -55 What am I missing here? rod IMPORTANT - THIS MESSAGE (INCLUDING ANY ATTACHMENTS) IS INTENDED ONLY FOR THE USE OF THE INDIVIDUAL OR ENTITY TO WHICH IT IS ADDRESSED, AND MAY CONTAIN INFORMATION THAT IS PRIVILEGED, CONFIDENTIAL AND EXEMPT FROM DISCLOSURE UNDER APPLICABLE LAW.
