power loss

[scorpionking]

2004.5 club car ds 48 v IQ I replaced the controller with a curtis 350 amp a month ago and every thing was fine, now with the gas pedal down 7/8 its fine I press it fully and it slows down to almost a stop? I did the speed sensor test and it does slow it down and beep ...any ideas?

Mcor

[scorpionking]

from what i can figure out I have the original mcor and I will need the mcor4? to be sure I guess I should take off what I have and look for the part # but the problem is intermittent and would rather have the new part before I take it apart ... Thank you guys for all your help

I replaced MCOR on my 04 and was told to get the original MCOR. It works good.

Look at the excellent write up TahoeDawgZ71 did on the different pedal groups/MCORS:

http://www.buggiesgonewild.com/elect...explained.html

According to that article, You will need:

MCOR1 to MCOR4 Conversion for DS - AM293101

Also, with the Key Switch off, pump the pedal all the way Down and Up about 30 to 50 times.

If the problem goes away for a while, the issue is definitely the MCOR protective coating has worn off on the upper section of the MCOR resistance track allowing it to get oxidized.

I know people like eBay but getting the OEM part from a sponsor won't cost more and you get their support and the users here can test to their support.

And MCOR selling sponsors like David keep this forum alive and make this exchange possible. I bought my MCOR at

when i buy one I will get it from a sponsor I was just under the impression from the sticky article that the original was discontinued?
