Checked wiring to motors, appeared ok. Took down main switch panel and uplugged all connections to slides switches.
Fuse still blew each time I tried to replace it.
Loom connectors appeared to be tight with good connections.
I cut the ground wire at the loom connector and ran ground directly to battery. Fuse still blew.
Reconnected original ground circuit with marrett connector.
Cut power wire and ran it directly to battery. Fuse did not blow.
Reconnected power wire with marrett, fuse did not blow.
Removed marretts, soldered connections.
Moved slides in and out repeatedly, fuse remains unblown.
Although I can see no problem with original loom connections, they must have been the problem.
Thanks for all your help.
