Greetings, Well... The Forward/Reverse relay got partially vaporized (something about not letting the motor stop when switching forward to reverse (or reverse to forward), so I went to the local electric used parts store but couldn't find a 36-volt relay. However, I did find a good heavy-duty 24v relay that could be used DPDT so I did a quick measure of the relay coil resistance and with a little Ohm's law had an appropriate sized resistor to drop the 36v to 24 for the relay. Now the connectors on the new relay are clearly more heavy duty so I go about replacing the connectors as I swap the new relay in. Now the "smoke test" - put it in neutral and try a little forward. Quick problem - it smokes... Check the wires - I must have one on wrong - do a swap. Now the motor spins forward so I check reverse and that works too. So, run the motor up to speed forward just to see if all the speeds are still operational. The motor steps up speed to match the "throttle" position, but what's this - the field weakening relay just smoked a wire. Well, I have basic forward and reverse (and speeds) but probably not higher speeds. Anyone with recommendations on what's causing the field weakening relay to vaporize a wire? --joe E-15 in Colorado (that Alltrax controller is sounding really good right now)
