Default power loss

2004.5 club car ds 48 v IQ I replaced the controller with a curtis 350 amp 2 months ago everything ran fine but now with fully charged batteries I have no acceleration and a loss of power after a minute where it will slow to a crawl?

Might try running the speed sensor test in the stickies, good place to start.

DS IQ or Precedent Speed Sensor Test

re checked the speed sensor all is well how ever I checked my batteries with a volt meter and Im only getting 49.5 for the pack and 7.6 individually always had over 50 and over 8 at full charge? another thing I did earlier this week was change my battery cables to the #4 I did them one at a time so no chance I rewired them wrong and I just found that my yellow battery light was disconnected plugged it back in and now light goes off and on while on charger as i said before I did have to do the mcor pedal pump 30-50 times but the last month its been running great until today... slower than usual acceleration then slowing to crawl...im lost as what to do next

Might need to check those batteries a little closer. You say you're getting 49.5 for the entire pack, but only 7.6 on each battery. 7.6 times 6 is not 49.5.... It's 45.6, which is DEAD

Evidently it hasn't been taking a charge since I changed the cables I charge it every night as I drive it everyday the charger needle shows it charging and I just figured it was charging. Any ideas as to why they quit taking a charge when all I did was change cables?

Did you perhaps drop or fail to connect the red wire that is coming from your charging receptacle to the main (+) connection of your batteries? This has happened before....
