Cummings motor allison trans. Need help please

[RKins]

Quick question guys I sent the TCU out to get rebuilt in the meantime while I'm waiting I decided to turn the key to see what would happen and the motorhome did not start at all it acted like there was no battery on the 1994 Dynasty is that normal? And while the TCU is out being repaired would that also cause the chassis batteries not to take a charge? Thank you

No idea on those questions - never tried that.

So I got the TCU back put it in and sure enough that was the problem thank you

 

[vandeusen]

Took it out on a test drive after putting the TCU in ran perfect more power than I needed

Glad you're able to enjoy her now.

That is a statement you don't often hear with RVs.

I believe with no TCU it does not talk to the neutral safety switch, it will not start if the TCU pulled out
