99 TXT DSC will not run and beeps when key is off

[99RedTXT]

1999 TXT DCS:
I have done all diagnostic checks that I have come across on the forum.
I know of three certain issues, (1) on my ten pin connector on my controller terminal 7 "blue wire that goes to solenoid" does not read 36v. (2) the solenoid gets very hot due to what I believe is being energized constantly. (3) When I turn the key to the off position the cart beeps constantly until I disconnect battery. Any assistance would be greatly appreciated.

volts ?

bad solenoid

1. No voltage on Pin-7 means that the controller is energizing the solenoid or that mo voltage is being applied to the other side of the solenoid coil (or the solenoid coil is open, but the solenoid is getting hot, so that isn't likely.)

2. The solenoid does get pretty warm, but shouldn't get too hot to touch briefly.

3. Is it a continuous beep or a series of rapid beeps? Also, does flipping the Run/Tow switch to Tow shut it off or do you have to physically disconnect a battery cable?

Do you hear the solenoid click? If so, when does it click? (Ie: When pedal is pushed. When put in Tow.)

You might have a bad controller.
If so, it's a good time to install a DCX400 and a heavy-duty (or super-duty) solenoid.

Ok when I go to the cart first thing this morning, everything is wired up and tight and i have beep, beep, beep, etc continually. Turn the key on all power reading are at diagnostic specifications even the terminal seven blue wire (B+). As I press pedal have an audible click from solenoid, beeping stops, but no movement of cart. The terminal 7 blue wire now reads no voltage. Turn the key off and beeping starts again, the tow/run switch will stop the beeping though. Johnnie any new ideas from this?

The DCS controller has a walk away safety feature that turns on the regenerative braking (energizing the solenoid is part of turn on the regen braking) and beeps the beeper rapidly. (See attached cut&paste from manual)

The DCS does not have a motor speed sensor, so it must determine the cart is moving by current flow someplace inside the controller.

What I suspect is that there are some shorted MOSFETs or transistors in the controller, so it sees current flow when there shouldn't be any and thinks the cart is moving.

Since the controller controls the solenoid and beeper, the controller is most likely bad.

JohnnieB or scottyb would the carts unlimited Pkg. #505DCS be what you would recommend?
400amp Alltrax (DCX400) 36-48v programmable
200a continuous/800a peak Solenoid in 36 or 48 volt
Suitable for all around use with stock motor and up to 22" tires

Also will my current charger work still with this mod?

Yes, the DCX400 is a Plug-n-Play for your cart and the 200/800 solenoid is adequate.
Unless you have done so already, your high current cable need to be upgraded to at least 4Ga (stock DCS was 6Ga)

If you suspect that you may up your pack voltage in the future, get the 505B kit. It has a 400/1000 solenoid that will work at 36V, 42V and 48V, so you won't have to change it out to up the pack voltage.

Yes your charger will continue to work with the controller upgrade.
The charger has to match the battery pack voltage. It doesn't know what controller is being used.

[I] got the 505B from Scottyb last week and have really been happy with performance,
I'm running 2 gauge cable and 36v and it has done everything that Scotty said it would

If you got the 505B, you have the Super-Duty (400A/1000A) solenoid rather than the Heavy-Duty (200A/800A) solenoid, so you need to correct the cart description in your signature block.

Might want to include the drive type also (DCS)

Cart in avatar appears to have stock height tires, what top speed are you getting at 36V?
