Hello, I am new to the forum and hoping to get some help. Our jacks were stuck and had blown one of the 150A fuses in the back. I went to change the fuse and when I started turning the wrench some sparks flew. So, I unplugged the motorhome and briefly turned off chassis and house batteries while I changed fuse to be safe. Re-plugged in and turned back on chassis and house batteries. Let sit for quite a while and went to try and start the motorhome to test the jacks and it’s completely dead. The screen won’t come up, the start button does nothing. My guess is I blew a fuse or something somewhere but having a hard time locating what might be the culprit or where the ignition solenoid would be. If anyone has any help it would be greatly appreciated.
