Re: Help an old fool out with his TXT
This is how I diagnosed a bad solenoid on a friend's cart -- even though it was clicking when the pedal was pressed, there was no movement. Jumped the large terminals on solenoid and success

9 times out of 10 the solenoid is good and the activation circuit is bad... I'm just saying you cannot simply bypass a solenoid and say it is bad unless you confirm it is being activated properly and not passing current. And if it is being activated (48v between the 2 small terminals) and it does not have 48v at BOTH big terminals then it is bad and bypassing it will only test the controller and motor - not the solenoid. I hope this helps See more here > http://www.cartsunlimited.net/troubleshooting-tips.html |

Re: Help an old fool out with his TXT
I disconnected the pack, removed the precharge resistor plus one lead to the controller. Then I ran a jumper from the negative side of the pack to the negative side of the solenoid coil. I also ran a jumper between the positive side of the pack and positive side of the solenoid coil. I had 37 volts across the coil. There is NO click. Unless someone tells me I've missed something, I'm picking up a solenoid tomorrow.

Re: Help an old fool out with his TXT
You did this with the small posts right?

Re: Help an old fool out with his TXT
Yes, pack voltage applied to 2 small posts while pack was disconnected from cart. While connected with jumpers, I measured 37 volts across the solenoid coil terminals, NO click. Coil resistance is around 140 ohms which seems to be in spec based on some info I found, but when the coil is energized, it isn't pulling the contactor in.

Re: Help an old fool out with his TXT
It's alive!! Finally got a chance today and changed the solenoid. The old girl woke right up. I also changed the microswitch in the pedal box. I don't know what had happened there but it was so far out of adjustment the roller had gotten in a bind and broken off the original one.
