Resto-mod, 36v to 48v...
Hi, I'm new to this forum and new to cart modification. I have built drag, stock, and one road race car, but have no real knowledge of electricity.
I've been lurking around here and got a ton of info! This is what I've done so far... Striped cart to frame. Built a battery box out of diamond plate that holds two 6v mounted in the bagwell. Purchased... 2awg welding wire and lugs. Alltrax 4865p. MZJ 400 contactor. PB-6. resistor 470 ohm Pre-Charge for 48 Volt Contactors. 48v battery Charger. 400 amp fuse. Contactor Prestolite JAM4801BBOC Reversing With Diodes 24 volt Coils. 2 more Trojan 105 batteries. (total of eight). I have a wiring diagram from Alltrax (doc 100 - 48 ) that I kinda understand but I have some questions. I've read about the plug brake option on here, but is it a good thing or not? The reversing contactor I bought is 24 Volt Operation for up to 72 volt systems, how do I make that work? The reverser is only rated at about 200 amps, does that mean if I use the MJZ 400 as the main that the 200 amp reverser only works when I switch to reverse? Sorry about the length of the post, I wanted to get you guys as much info as I have. Thanks for any help! Randy |

Re: Resto-mod, 36v to 48v...
After reading my long and rambling post, I think my questions are unclear.
1. Do you guys think the reverser I bought will work in my system? 2. If so, how do I get 24 volts to it? 3. Would I be better off buying a reverse contactor with 400 amps to match my main contactor, with 12v coils? I'm not sure I'm even asking the right questions or that I put this in the right forum. Any advice would be greatly appreciated! Thanks, Randy |
