Thread: M4-ATX gets stuck in a power on/ power off cycle

Try this....first time I tried uploading to youtube

Bump

I RMA'd my M4-ATX. Here's to hoping that the new one that comes in has the issue resolved.

Not entirely sure the M4 is the problem although it is suspect at this point. Also on my list of potential root causes is the Aux battery (I will be replacing that as well)

Got the new M4 in and for good measure I replaced my Aux battery.

Here's to hoping the issue is resolved

Since it look likes I am on my own with this issue at this point I can only hope that this helps someone experiencing similar issues...

BTW even after replacing the battery (which was on its last leg) and replacing the M4-ATX I still experienced (twice today) the power on power off cycle issue.

I have been in contact with the makers of the M4-ATX and will speak to engineering some time on Thursday to figure out the next step.

In my opinion it is either an issue with the firmware or with the hardware common across all M4-ATXs, issue with my motherboard, or a situation where one of my rails is overloaded

Today I found an issue with the IGN wire. The solder joint was faulty. I replaced it with a solid connection and ran all day without the issue arising. Still testing though.

Damn... Had the problem again. It ran for almost two days without issues.

I did a fresh windows 7 build and it didn't help

Hello,
I've also had the same issue with the M4-atx power supply. I also have an annoying hum that I'm quite sure is due to this psu. There was a thread called "everything you need to know about your m4-atx" somewhere on this forum. In this thread the aforementioned problem was fixed by placing a diode in series with the ignition connection on the psu and a capacitor from the ignition line to ground.
