I was very nervous about firing it up the first time. Only thing I would say is to not connect anything other than the main + and- cables and the charger for now. You can hook up the accessory 48 volt later. Best of luck, and it has been a pleasure going through this with you! |

Re: 1981 Lithium conversion possible?
Update: Had the thermal tripped when I bolted the 250 breaker to the Positive post so there was no load possible unless there was some crazy short... so the real pucker was closing that circuit... absolutely nothing happened which was perfect! Checked lights anD all accessories, worked fine. Bit the bullet and took the old gal out for a 3 mile shakedown cruise (as we said in the navy) and stopped every mile to check for hot spots. Main concern was some of the old 48” x6guage wires I have going to the motor from the F/R switch... no real issues there.
I did notice my solenoid was piping hot though after the 3 mile stop... I assume that is not normal and may indicate that a beefier one is needed... go figure, it has the most wires on it. Any suggestions for a size / model? Plugged it in for about 5 min until it went solid green, then hooked up the LCD monitor and set it to 100%... after three miles and resting a few hours it is now sitting at 88.6%... that means I should be able to get a good 18-20 miles on a charge down to 25-28%... that sound right? |

As far as mileage, my 72 Ah gets me a solid 39 miles as proven by a 27 mile ride in one day. At 36 volts, your range might be less, but I'm still learning about the operating data of lithium batteries. Felt good to be cruising again, didn't it? |

Re: 1981 Lithium conversion possible?
I went ahead a ran over to my local cart shop and got a bigger solenoid, I just didn’t like how hot the solenoid got, there are a bunch of wires crammed on it and the heat can’t be good...
The new one should be a 200amp and is drastically larger. I pulled the old one out and it has 15amps written on the side, but that can’t be right... took it for another 2 mile test run today after the swap and the solenoid had no heat what so ever... mission accomplished |

I can't see that being a 15 amp solenoid but if it is black plastic and smaller terminals, it is a 36 volt relay, not a solenoid. It is a wonder it worked at all. |

Re: 1981 Lithium conversion possible?
Well... it had to be a solenoid... it was one of the 5 for the original resistor coils. Pretty sure there is no question about that. I’ll see if I can get a picture and post it and we can decipher this mystery...
