Re: (ET) Voltage dip

Ralph,

The easiest way to test the batteries under load is get a jumper the size of the battery cables and jumper out each battery one at a time. The controller will run on 24 volts (actually 24-48 volts). Run the ET around normally. The only difference you would see is in speed. When you jumper out the bad battery (if that's the problem) the symptom will not occur. The current and voltage both drop because a resistance is being added to the circuit somewhere, most likely in one of the batteries if nothing else is getting hot.

Steve, I have 4 computers and none of them can run XP. I use a legal size scsi scanner and a CDRW that cannot be made to run on XP. I also run CadCam software that needs dos and will not run on a machine with XP. I can't do a load test because the problem doesn't last long enough. I will have to take the cover off to check the solenoid temperature.

G M Bauman, The internal thermal switch is wired in with the seat & brake switches so it should be working. I pulled a 800 pound roller around for 2 hours and it didn't shut off. I heard that motors running on PWM controllers do run hotter.

Jim, The main disconnect switch is the new style from Bill Gunn. I installed it last fall.

Michael, The AllTrex doesn't use forward/reverse contactors, it is solid state.

I was wondering if I had a cell in one of the batteries that had an intermitent short, If I do wouldn't it only drop 2 volts? I appear to be dropping about 8 to 12 volts on the fuel meter. The fuel meter is new, I just installed it last month. It checks good with my other voltmeter. I don't understand why when the voltage drops the current on the load meter also drops a little. If I had a short circuit the current should go up? The batteries stay cold, all battery connections and cables are new and they stay cold.

Thank you for your thoughts
