CruiseAir Control Unit Ribbon
Can someone identify exactly what this Ribbon does in one of my Cruiseair modules?
I have four Cruiseairs, but only three of them have a control box module with this Ribbon attached. If you notice from the photo, this Ribbon seems to have been burnt at some point. Don’t know if it’s recent or not. All four Cruiseairs are working, although I had an incident with one of them shutting down last week in extreme heat.
Also don’t know if this can easily be ordered thru AAP and then installed by me.

Tim,
I think that’s the ribbon cable for the SMX Control and if so, is likely a home run to the SMX panel.

After some more research, found out this is just a six-inch 6-pin Ribbon cable which connects the black box that Marathon puts on the grey box Cruiseair. It controls the Aux heat for my SMX control box. In this case, it controls my Webasto since it’s on my cruiseair for my Salon.
Less than $5 part …

Tim, There is no such thing as a $5 repair part on a Prevost.
That must have been a typo and you left off a zero or two.

It’s a shame when the shipping is three times the price of the part 🙂

The ribbon cable doesnt burn a trace like that for no reason, what failed that caused this?

When I talked to Marathon, they indicated that some owners had replaced these ribbons and put them on the wrong way. These ribbons have a ground and they can be in put in backward. The cruiseair grey box is a 7-pin connection and the marathon black box is a 6-pin connection so there is a chance to put these on the wrong side.
The cruiseair that this black box was on was replaced and is not original. So whoever replaced the cruiseair could have put the ribbon on the wrong pin when reconnecting the black box to the cruiseair box.
To solve that problem, Marathon now makes the ribbons to only go on one way, with the ground properly seating itself in the right pin.
