suddenly stopped-2001 electric TXT 2+2 w/ PDS,

lvandyke

went to take my 2001 electric TXT 2+2 w/ PDS for daily 1 mile run w/ my dog and 200 ft out f driveway suddenly stopped. Was on charger last nite- batteries read av 6.2 volts. was able to reverse very very slowly and barely back into driveway. if not batteries-what else? Controller?

Put the PDS controller into diagnostic mode and listen for error codes.

Text at bottom of attached label tells you how to get into diagnostic mode.

thanks, did some research to find how to put in diagnostic mode-pretty cool. getting ready to do so now-plus check back of direction switch on Dash- {PDS style

lvandyke

so put it in diagnostic mode after checking voltage on batteries, all are 6.4 av except one at 5.4, all terminals look good/tight. cells float all 5 balls on spec gravity tester, fluids full.

code only beeped 3 times- then nothing after pause. no codes detected?
Maybe clean all terminals w/ baking soda paste- then recharge. ??
before starting this last round- tried moving forward/reverse- only shuddered and moved maybe few inches

That one battery is shot. You can try hooking up a volt meter on that one and drive to see how low it drops, but 6 volts is dead. You are at 5.4 volts. That's zero percent SoC.

What do the others read 12 hours after a charge completes to two decimal places? Each, not average.

What is the date stamp on the batteries? Are they all the same make/model? If they aren't too old, you may be able to find a used battery the same make/model/age as the dead one(s).

Bad info yields bad advice.

I have it back on charger now- will check in the morning, each battery. all batteries same, at least 3-5 yrs old I think. I read about readings on controller plugs J1, J2, etc. I could try that to rule out wiring- but first the battery charge. When starting charge- charger went up to almost 10 volts, settled back to around 7 volts in less than 3 min.
thanks for advice- will check in tomorrow after charge.

so charged overnite- total charge was 40.2v, individuals were 6.4 plus/minus .2
the suspected bad battery was 6.2
took off charger (had already shut off) tried to move- only shuttered but would not move f/r.
tested suspect battery and read 5.4, all others were 6.2, total was 36.5
these are US Batteries- marked 12-15
time for new battery?
can I mix brands?
what about a sealed one w/ 5 others still original and good?

thanks in advance for your knowledge.

You can replace the bad one with a used battery, with same age, Amp-Hours, and ideally same make/model. It may give you another year before you have to replace all. You should connect a hand held digital multimeter across each battery and read the voltage while trying to go. The bad battery will probably drop WAY down while trying to go. If the others are OK and you don't want to replace all right now, go used.

I wouldn't mix and match other battery types. You'll have to look up the date code, to see how old they are.

thanks- post reads J-5, tag marked 12-5, so either way- about 4 yrs for all. right now I can only afford one battery but know I'll need other 5 this yr probably.
I'll need some advice on breakin of 1 new battery
