slide blowing fuse

[bduemig]

I have a 2019 Georgetown XL 378 triple slide. The other day, I brought the slides in in extremely cold weather and it blew the 15 amp fuse in the DC box above the batteries. I changed the fuse and the slides worked. Went to put them out again while on the road and it blew the fuse again. I brought out the 2 smaller slides, but when activating the big slide, it blew it again. Leveling jacks and fine.


Does each slide have its own solenoid that may be shorting out? Could it be the extreme cold? I have not changed the fluids for cold weather operation.

Each slide has its own solenoid valve which is energized via the system controller with input from the slide switch. The pump motor is reversable via the slide switch (energizing the Trombetta relay in one direction or the other) mounted on the pump motor). Power to the switch is via the BCC from a fuse within. The relay that is controlled by the ignition switch for slide defeat when ignition is on is also in the BCC with output through that fuse to the slide switches and this is probably the fuse that is blowing. Have not had to many faults to address for the slides so this input is a semi educated guess at how my 2012 GT378 system works.

Moved thread from the Tech and Repair section to the Georgetown sub-forum for better help from other Georgetown owners and possible factory support.

Evidently some GT378's do not use the reversable pump motor and instead use an electric selector valve within the hydraulic manifold and a one way pump motor drive. I think all other functions remained the same.

The fuse that blows says 'slide power' on the BCC door panel. A schematic I just looked at says the far right fuse is for the ignition cutout. Why would only one slide cause that fuse to blow?

That's as stated and since that BCC output is the 12Vdc to all slide switches therein lies the dilemma to which I have no answer. Each slide valve has a (2 wire) connector to it so you might swap 2 slide valve connectors to see if it doesn't move with the swap indicating a bad valve. If it moves with the swap it may be a controller issue. Shooting at straws here and don't want to lead you on a useless tangent.

Thank you for the suggestion. Nothing is useless at this point. Whatever I do will at least eliminate that part of the system.

I think this is the correct photo for your GT and maybe could swap the 2 valve connectors next to each other.

That is exactly what I needed. I couldn't figure out which selonoid is for the main slide.

This is the install in my GT378. Maybe will help. Good luck.

Well, it looks like it may have been a bad switch. I replaced the switch and everything works. We will see what happens when I bring the slides in when I leave here in a few weeks.


Thanks for all the help.

Slide blowing fuse

My problem was with the GFCI in the bathroom tripping when the slide was brought in. Long story short, the coiled electric cable for an outlet on the slide had rubbed on the opening and created a bare spot on the black hot wire. When slide was out the GFCI would reset but when slide was in the bare wire laid on the metal square bar that turned the slide and caused a short tripping the GFCI.
