How do you break down trooper? - Electric Mobility Shoprider Electric Power Wheelchairs Scooters Trooper

Question edited for clarity. Wrong type of break / brake.
Question moved to model category.

Check the brake switch with a meter first. Then check headlight relays and fuses.

Are you putting the thermostat in spring side down?

When mine came on it was the main computer system for the antilock breaking system - very expensive to fix. Needed the main componet that sensored the breaks & fluid to the breaking syserm - cost 2800.00 for the part alone then the labor on top of that.

just a suggestion did you check to see if there is a bleeding sequence for that specific car

Get your vehicle's brakes master cylinder checked, tht could be the problem.

this transmission doesn't have one. there is a reservoir u have to check with a special tool. the oil they used for this transmission doesn't need replacing, it is made of an oil that doesn't break down apparently, so i read

Sounds like you have the wrong oil in the engine ? Has to be 5/30 fully synthectic.
Others break down when hot and affect the HUEI settngs .

The switch located on the brake pedal.

What grade of you do you have ? must be 5/30 fully synth or it breaks down when hot and makes for a misfire.

Usually elecrical, switch, wire, connection, or mechanical adjustor on shifter linkage. I had the retainoing bolt break on me for no reason.... No biggie just a pain in the Donkey :-)
