Pack voltage drops under load but individual batts don't?

[ScottBeowulf]

Hi and a quick thanks for all of the informative posts available on this forum. I've had a few problems with my cart in the past and I've been able to get them worked out thanks to the info available here.

Now I have a problem that I can't find previously posted (apologies if I missed it). I have a 36v EZ GO that after an overnight charge will run for a minute or two and then just shudder (F & R). I checked the pack voltage and it is about 38v standing, but drops to 28v under load -- the weird thing is that each battery indicates about 6.5 volts under load, showing no significant drop. How can the pack voltage drop if none of the individual batteries drop?

Sounds like a loose connection somewhere to me. Check and double check all the connections.

Agree with that, that much voltage drop will generate some heat also, so check for that also. - RAY

Awesome thanks guys, that was it. I had checked the connections and cleaned some corrosion before posting, but on your suggestion I looked again and found that the corrosion had eaten through a good bit of one of the terminals. Replaced that terminal and cart runs great. Thanks again.
