Advanced DC motor input or experience?

[brunson67]

Does anybody have any information or experience using an Advanced motor in their cart? It's a 5.5 HP, 5600rpm, 48 volt motor.

If you are talking about the AMD #7144, I am using it and it works great. Top speed is 38mph on flat ground with std gears. I do have the Curtis programmer so I was able to optimize the controller settings.

My local cart shop is selling it to me, so I don't have a model number yet. I'm using a 700 AMP FSIP controller, super duty solenoid from Scotty, and #2 cables throughout with OBC stud. Its a stretched 2001 Club Car, lifted, running 25" tires. I am going to switch to 23" once these wear out. And stock gears.

That is some danger zone rpm. 8000+ !

It sure would be if I was running std size wheels/tires. Bigger tires reduce the motor RPM.

True. How tall are your tires?

[brunson67]

Based on the specifications, it appears to be AMD #7119.

You get your brake issue lined out brunson67?

Funny you ask, This has been driving me crazy - At first I thought it was the master cylinder, its a Wilwood 260-11097, 5/8" bore, tandem master cylinder, obviously a great brand, but I thought maybe it was defective, as the piston was not returning, causing the brakes to severely drag. As I had mentioned, I designed this kit and built it many years ago, before there were kits on the market (my cart was a long project!), so Wilwood master cylinder, Club Car Carryall calipers, Honda civic rotors, my own brackets, etc. What I discovered last night is when I unhooked the rubber lines from the remote reservoir, I had a trickle of brake fluid coming out, very small trickle in little bursts, I then un-screwed the so-called vented cap on the reservoir and the flood gates opened up, full flow of brake fluid. I think I have a faulty vented cap. I'm assuming this is placing a sort of vapor lock on the system, not allowing the fluid to travel back into the reservoir as pressure builds. Any thoughts on this?

Sounds plausible. You should be able to determine pretty quickly if that was the issue. That would be great if that's all it took to fix it!
