reverse only even in foward position
Hi, I have searched the forum before i asked, maybe Im not wording it right. Anyway I have a 97 txt with dcs, it has the tow/run switch and the two micro switches for forward and reverse. The problem has been intermittent for a while and is now constant. with the f/r selector in reverse or forward position it on goes in reverse. i have checked continuity on both switches.the f-1,f-2 wires can be reversed and its forward only. Is this a bad controller? I did have to adjust the throttle pedal ring where it contacts the micro switch it was keeping the solenoid energized all the time. any help would be greatly appreciated

Re: reverse only even in foward position
I am 99% certain it is a bad controller. Stay away from refurbish - Go new aftermarket.

Re: reverse only even in foward position
Any specific vendor you would recommend? Not looking for anything special just stock.

Re: reverse only even in foward position
It probably is a bad controller, but I'd check the voltage on Pin-4 at the controller just to be sure.
Should be 36V only when F/R is in R. ------ The DCS controller defaults to Forward and has to be told to go into reverse. (IE: Pack voltage on Pin-4) The two microswitches on the F/R are Run and Reverse rather than Forward and Reverse. The Run microswitch is closed in both F and R while the Reverse microswitch is closed only in R. ---------- If it is a bad controller, don't waste your money on a stock DCS (Curtis 1206SX) controller. It was a failed design (No under voltage protection). |

Re: reverse only even in foward position
pin 4 has 36v at all times. I even unhooked both micro switches and there is still power

Check for voltage on pin-4 of the loose 10-pin connector. The logic gate inside the controller that is connected to pin-4, doesn't draw much current, so it wouldn't take much of short between pins in the MOLEX connector to trigger it. That isn't it, the controller is bad. |

Re: reverse only even in foward position
no voltage on loose connector still 36v on pin 4 on the box. Does that mean a bad controller?
