Default Re: '03 IQ is a still a Nightmare

THE MYSTERY deepens or am I getting closer to solving it?
I ran the pack voltage down and the charger now runs for about 2 minutes and pops the little breaker on the front of the powerdrive. Some investigation reveals a short to the frame? From the battery pack Positive to frame reads 48v.... So I begin disconnecting things to see where it stops this foolishness
the cuplrit is the F1 and/or F2 Terminals? The motor shows no unusual continuity between any F and A terminals but when I disconnect both of the F terminal wires at the controller the 48v reading drops to 9.1v ( which is greater than any 1 battery). Reconnecting either F terminal to the controller results in 48v at the frame? Motor was dismantled and inspected. Controller was bench and cart tested..... WTH could this be?

You may have already checked this and I missed it but here goes anyways....
You need to find out if this voltage is "Ghost Voltage" or real.
You can make up a 5amp fused jumper wire with alligator clips and go from main pos. to chassis....
if it doesn't blow then go from main neg. to chassis. If fuse doesn't blow then voltage isn't real. If fuse pops, then you have a leak.
Disconnect main pos. and neg.
Un-hook motor wires
check for continuity between any of the motor terminals and the motor case or frame. Should not be continuity...if there is then motor is shorted inside.
Also, No one has put a chassis ground of any kind on this cart? Like for the lights or any accesories?
I have had customers hook-up a chassis ground on a golfcart not realizing it is a closed loop system. Not an open loop like a car or truck.
Using a chassis ground on a golfcart is asking for trouble if you have a major component short out....most motors and or controllers are not fused.
I have seen EzGos with a chassis ground burn the coating off of the brake cables because of a motor short. Voltage found the path of least resistance.
I don't know if this will help.....just grabbing at straws at this point.

I appreciate your help. I have check all of the things you mentioned..... I think it is in the wire harness .... Anyway I hate this cart now So I dropped it off at the local dealer and said call me when it is fixed I give up. If and when it gets fixed I will post the solution here. This has been the cart from hell. I will never want another CC IQ
p.s.
If they can't fix it you are all invited over for target practice and a bonfire.....

I had an IQ giving us a fit too. My guy swapped out 2 controllers, solenoids, computer, MCOR, keyswitch, Tow/run, F&R......You get the picture...so I gave it to one of the other guys......4hrs later, he tells me what I already know. The solenoid trigger wire ground...small blue wire with white runner was dropping out. Just like the older series carts would when a computer failed and you could jump from main neg. to small yellow to bypass OBC and get solenoid to engage.
Anyhow, small blue with white runner would show neg. voltage until you turn on key , put in run, mash pedal....It would then drop to zero.
So, jumped to main neg....solenoid would then engage but no movement.
Fri. @ 5am I go in and pull a harness out of a running cart and 20min later cart is up and running. I didn't get a chance to tear into harness but I will tomorrow...Mon. I will post what if anything I find.
Here on the other hand is what I did with my 2006 IQ. I carefully took out my Razor knife and snips and.......................06 CC IQ DS Frame 4x12's.jpg

CUT ITS STINKING.... ROTTEN.... FILTHY....NO GOOD GUTS OUT!!! IQ GUTS.jpg
It will return in its next life as a 72v series cart. Like all good little carts want to be when they grow up.
