4wd not working in forward gears.
I recently picked up a 2008 Prowler 650 on craigslist and I am real happy with it. The previous owner added a four seat conversion, full aftermarket cage, HID lights, light bar with 3 lights, PRP seats all around, 3 point seatbelts, soft top cover for cage and 2 inch wheel spacers. The cage, seats and skid plates also have Rigid Industries emblems cut out and stitched on it. I also put on new ProComp tires yesterday. So slowly but surely I am going thru everything to see what has been done to it. The one thing I can't seem to figure out is 4wd will not work in H or L but will engage when put in reverse. If I activate the locker 4wd will work in H, L and R. I measured the voltage at the switch and found the white/red wire has 12volts going to it in 2wd but when put in 4wd it only drops down to 9volts instead of 0volts to engage the 4wd. I found the previous owner had bypassed the reverse speed control, so I am assuming the problem might be in that area. But I am not sure how the PO had done the bypass. If anyone has some thoughts of where to look or what to check I would greatly appreciated it. Otherwise the whole family loves the new toy!
