Re: From 36v to 42v conversion
Assuming I do upgrade my solenoid, what do I really need? What model solenoid (MZJ-400A?) and if I do go that route, what resistor and/or diode would I need to use? I would like to do this much right away, but unsure as even on your website the 42 volt option isn't mentioned as an option.

Re: From 36v to 42v conversion
I have a 2006 PDS Western 36v cart running on 42v. This past weekend I just installed a 48v RoyPow and everything works....except it doesn't move. After checking a few things, I put the controller in diagnostic mode and it gave an over-voltage code. (I suppose it can handle 48v but not 52v). Now I think my only real options are Navitas or Alltrax DC controller and maybe also have to replace the motor later with a 48v DC (if it cooks the 36V one)..or...just convert to 48V AC now.

As for the solenoid I have a completely different cart but similar situation (in theory). I have a 48v cart that I run at as much as 57.6v. My stock 48v solenoid lasted 2.5 or 3 years after I converted, but to be fair it was already 7 years old when I converted to lithium... So it could be that a decade was all the service it could handle. Anyway, I upgraded to an HD 48v solenoid from Scotty and it's been working fine since. I'm only 1.5 to 2 years in on the HD solenoid (I guess) but it's working fine... And I'm using the 48v resistor too, I never changed it to handle higher V. Here's what I'd recommend. Buy the HD solenoid. Run your current solenoid and don't worry about it. When the HD gets here, put it in and don't worry about it. It will fail in a decade. I'm OK with that but if you aren't create a reminder on your PC to replace it in 9 years. I'd run the 36v resistor but if you're worried about it JohnnieB posted somewhere how to calculate the correct value for a different V solenoid. |

Re: From 36v to 42v conversion
Our 36/48 volt SW180 is perfectly engineered for 42v operation. It actually has a 42v coil which allows it to operate on 36 to 48v and stay within it's 20% voltage tolerance. I don't see any benefit of 250 vs 470 ohm precharge resistor in the 42v application. If using the Alltrax XCT controller it does the precharge internally - so no worries, just put the bigger 3 amp voltage suppression diode on the solenoid coil.
