'97 Sea Ray 240 Sundancer. Yesterday, I was trimming the boat out and could not get the boat leveled. I shut the engine off and pressed one switch, then the other and could not hear the pump run. The 20 amp fuse was blown and I replaced it and pressed one of the buttons and the fuse blew.
Went back to the marina and unplugged the pump unit, replaced the fuse and pressed the switches on the dash and the fuse did not blow. The wiring at the switches looks fine - nothing is chafed. I could not see anything wrong with the wiring at the pump or connector either.
I plugged the pump back in and replaced the fuse and pressed the button - I heard the pump run for about two seconds and the fuse blew again.
I am thinking the issue is either a stuck ram or something in the pump is bad causing it to draw excessive current. I'm currently 400 miles from home and tools are limited. I may wait until I return home to troubleshoot this issue but it would be helpful to have some ideas on what to check or if there is something simple that I may be able to repair at the marina (not likely).
Thanks.
