Re: 36v cart not running
That is correct. The stock solenoid is not rated for the increased amperage. Anyplace in the system that you have a component not rated for the working amperage you will have resistance which results in heat which will result in component failure.

For the perfect system, the total sum of all voltage drops should be equal to the total of the power being supplied. Anything less is lost in heat due to restance of some sort. I understand the Resistance = Heat thing (E=IxR). Thank for helping a newby out. |

However, there are no perfect systems since batteries have internal resistance and the copper conductors in the high current cables intrinsically have resistance. 25' of perfectly construed 6Ga high current cables in perfect condition loses about 99W per 100A of current flow, 4Ga about 62W and 2Ga about 39W. If any cable, connection or component is getting too warm to hold onto, it has too much resistance in it and should be repaired or replaced. |

Re: 36v cart not running
Thanks for your input. At first I could not figure out why I had to have a newer solenoid. But knowing that the controller was pulling more amps made sense. I also need to look at the F/R selector bolts. They are getting hot. you can see the discoloration in them. It may be because they are loose. Don't know. I will have to take the time to dig into it this weekend.

Re: 36v cart not running
Yep, that is about what they look like. Just not enough to melt the housing yet.
