Solenoid Cables Burnt
 

While driving in heavy rain my cart stopped and I could smell burning wires. When I got home I saw the wires melted on the solenoid. The wire that goes from the solenoid to the F1 terminal on my controller had the end burnt off,the resistor and the diode on the solenoid were burnt,along with the wires that go to the motor(black and white) were damaged. All the damage was done on the one side of my 48v solenoid. My question is what to do from here. I can repair the cables easy enough but what caused this and how do I define how much damage was done.http://www.buggiesgonewild.com[ATTACH][ATThttp://www.buggiesgonewild.com/attachment.php?attachmentid=125989&stc=1&d=1443651 561ACH]125989[/ATTACH][/ATTACH]

Re: Solenoid Cables Burnt
 

The burned wires were likely caused by a solenoid failure. Thats where i would start, the terminals are likely screwed up now anyway.

Re: Solenoid Cables Burnt
 

There should not have been a wire connecting any terminal on the solenoid to the F1 terminal on the controller.

Undoubtedly, you need a new solenoid and a new cable or two, but make sure it is wired correctly.

You may want to upgrade the solenoid to a 400a unit at this time.

Thanks to all 3 who responded, thanks to cgtech, I took your advise and ordered a 400A solenoid from scotty b(carts unlimited )this morning,even before I read scotty b's response. Now Johnnieb's response, I'm really glad you pointed out that the F1 cable should not be connected to the solenoid, after looking at the burnt cable I see it was just burnt in half at the solenoid lug by being next to it. The old burnt solenoid I took out was a MZJ-200D.

Hate to say this, but, if the F1 was fried in half, the controller is likely shot. The F1 & F2 wires really hate being "messed with" by voltage from anything else. We'll see soon. I hope for the best.

Honestly I have never seen or heard of F1 connected to the solenoid. The fact the cart ran baffles me. Is this some kind of go fast trick?

Re: Solenoid Cables Burnt
 

If I read the statement highlighted in blue right, the F1 cable was not intentionally connected to the solenoid, it just was routed close enough to the stud that got hot to melt through the insulation, which then shorted the F1 cable conductor to the stud, which in turn put B+ from the battery pack into the Field winding circuit, which drew enough amps to burn the 10 Ga copper conductor in two.

As CG said, it the battery voltage did get tied to the Field circuit, it very likely took out the controller. In fact, it might have taken out the Field windings in the motor also.

Hey! Keep your eyes on the road :lhmo:

Re: Solenoid Cables Burnt
 

Jonnieb is right,the wires were routed too close to the solenoid and were taken out by the heat, I mistakenly said the wires were attached to the solenoid.I will let you know what happened on Monday when the solenoid comes in. The wires are repaired so all I have to do is to install the solenoid to see how much damage was done. Wish me luck.
