Trombetta soleniod

[ep120794]

I have a 2005 Endeavor with a Trombetta solenoid. I have seen people mentioning this get hot to the touch. When would it be hot? After having driven for awhile? I am plugged in at home to 20 amp service and it is ice cold.

This may be what is called the Salesman Switch solenoid. When the switch is turn on it closes the solenoid and provides 12 volt power to the coach. Mine stays warm all the time, not hot. If it is hot the contacts may be going.

Trombetta makes lots of different solenoids, what is the one you're referring to control.

I am in the process of replacing one on my motorhome, the only time it is activated is when I depress the MOM switch. If one set of batteries is down then it will get warm if I hold it in very long. Yes I have another one that disconnects house batteries.

I have a Trombetta model 114-1211-010.

Should the Trombetta be cold, warm, or hot when plugged into 20 amp shore power at home?

If this relay is in the battery compartment it probably has a purple wire going to it.

Measure the voltage on the small leads. IF one is 12.5 or over and the other is zero then the solenoid should be warm or even hot.

If there is no voltage on the purple wire, use a small wire jumper from the large post of the solenoid, either will do, and touch it to the purple wire. If you have a handy fused lead for testing things so much the better.

Use some insulated tool such as needle nose pliars with coated handles. You can get a startle when the monster goes click so be careful in there.

Mine bit the dust this year. Trombetta 114-1211-020. I have to order one, I bypassed it for now. Is there a better product out there?

This item is the Trombetta with silver contacts. Much better unit than the original (-010).

The Trombetta is engaged when the battery boost switch is depressed or the engine is running and the chassis batteries are at full charge. It bridges the chassis and house batteries to charge the house batteries when the coach is running down the highway. It serves no purpose when plugged into an AC connection.
