Infineon R12 regen voltage mod abnormality?

[m52 power!]

I was just going to modify my R12 resistor from 1.2K to 1K to increase regen above 75V (https://sites.google.com/site/shelbyelectro/controllers-and-electronics/controllers/infenion-high-voltage-regen-r12-mod).

When I opened my MCU I probed R12 with my fluke dmm and it measured .894K ohms? Is this a bad resistor, or intentional?

Try using a different scale on your meter. Looks like you're using the x1K scale. Try the x100, x10, or x1 scale. And make sure you have a good battery in it.

I use a fluke all day at work. I've tried another meter and it too reports 894 ohms.

I got a reply from Lyen that he has already done the resistor mod, DOH!

How did he do it so you couldn't see it. My non Infenion 72V controller also had a 1200 ohm resistor. It had an LVC of 62V and regen wouldn't work above 78V. I found that lowering it to 800 ohm raised LVC to 84V and allowed regen to work to 100V.
