I took a quick look and skipped to the part where they mount the controller, I totally disagree with what that guy is saying.

Think about it, the components mounting plate could be made of anything, it would not make sense to make it out of something as expensive as thick aluminium if the purpose was just to hold components.

The aluminum mounting plate is a heat-sink for the controller and OBC.

Allowing an air gap between the controller and the heat-sink is a huge display of lack of electronics understating and how heat transfers.

If anything, You would want to add some heat sink compound paste to the bottom of the controller to provide better thermal transfer.

I agree good way to take out a brand-new controller

I watched the video. I'm debating whether to redo my mounting to make it horz. The way mine is now I had to cut the bottom cover to make it fit in. So now I'm going to have to devise some sort of cover to protect the electronics, possibly an aluminum plate bolted to the frame. Right now I have 180mph duct tape on it.

On the other hand with it horz install the wires get to crammed in and it looks very tight. One solution might be to mount the solenoid on the battery side of the plate. It looks like there might be clearance. That might speed up my desicion for a DPI charger. (to do away with the OBC)

Then again maybe somebody who sees this will have a better idea. Btw it runs great and the hills here in East Tenn that I would only 13 mph going up before I now get 20mph. This is with a AMD 6 HP motor.

I wonder if You can re-position the OBC so it mounts from the Battery side of the component plate.

It would only protrude 1/4 inch into the battery compartment but would provide a flat surface for the controller to mount horizontally on the other side.

I don't like the way he mounted the controller also, I have pics of mine before I returned it, the plate on the 2008.5 is slightly different than his so that is how I was able to mount it. I used heatsink compound also, was messy but I feel it would help with heat transfer to the aluminum plate.

The Curtis 500 amp controller was plug and play, I could of adjusted the sensitivity of the Alltrax program, and smoothen out the throttle or replace the MCOR being 2008.5, but now Sergio & ScottyB has a fix for that It wouldn't be an issue. I didn't like the adapter being exposed also, I use that cart in rough terrain so didn't feel it would hold up as well, read there was issues with the adapters over time. The main issue I had was the controller thought I had Low voltage, that was most likely another setting that could of been changed in the settings, I would of had to either send it back to hope they got it right or buy the cable and deal with trying to program it myself. I returned it because I specifically didn't want the Alltrex in the first place (wanted GE But ended up with Curtis), about that time Curtis had came out with the 500 amp upgrade and felt that would be a better fit. I have no regrets, works flawlessly, even smooth pedal with the same MCOR.

Scooterman I think your first post was right on. After reading ScottyB's remark about the faulty adapter problem with the Alltrax, I am betting that is what is wrong with mine.
I do like that mounting horizontally, I did not need to cut anything that would expose the electronic devices, jj. It is tight getting the wires on but by attaching the wires first before mounting, it is possible.
Sergio I worked is industrial maintenance and always used thermal heat transfer compound when replacing SCR's, triac's, diac's and other heat producing electronic components but drives usually were make with fins on the back to space them off the mounting plate and allow air movement, of course fans are used to move air across the drives. These controllers don't have fins or fans and may rely on transferring the heat to the mounting plate. I really like your idea of moving the OBC on the battery pack side of the mounting plate. Mounting the controller with out the spacers would be easier.
Another question I have is the Neg. wire running through the OBC. I changed my 6 gauge wires to 4 gauge and could barely get through the opening. What do people do when they upgrade to # 2 gauge? Does the OBC monitor current draw from the cable? When does the terminal size limit the gauge of the wire?

You need to use a stud through the OBC, here is an old post I did about my opinion for the reason why that is the case.

Why You should run the negative cable through the OBC

Great thread explaining my question! I had not thought about the stud, sure would make the mounting plate easier to remove or lay flat when working on rear mounted components with the Neg. wire removed.
I will stay with the #4 cables I ordered and installed, at this point. Didn't like having to cut one of the terminals off the Neg. cable and re-crimp a new one on a store bought cable.

JJ - I said I would post my controller horizontal mounting photo when I figured out how, here's hoping. Dan's iPhone Pic's 060.jpg
