RE: catalina27-talk: strange electrical problem and bilge pump advice

[The Emmerichs]

Sebastian,   I'm don't think I can help you with your problem but I can tell you how mine is wired.   I'm the 4th owner of this boat, I don't want to assign blame but I would be inclined to blame one of the PO's rather than Catalina.   Bilge Pump - Mine is wired directly to the switch on the panel and then directly to battery 1.  When the panel switch is on, the pump works.  The position of the battery switch whether off, 1, 2, or both doesn't matter.  I don't remember if there is another fuse in the wiring other than what is on the panel.   Stereo - My unit has three wires, two power and the third a ground.  One wire powers the radio, the second the memory which retains the stations settings, treble, bass, balance, and fade.  Whoever installed the radio wired both together so when the panel switch was turned off, the radio lost all of its settings.  I recently ran another wire to battery 1 from the preset connection so I would not lose the memory when the panel switch was turned off.  In this wire or connection I installed a fuse.  I don't know if losing the memory connection would cause the radio not to operate, and yours may be different.   Hope that all of this rambling around will be of some help.  Whoever did this re-wiring on my boat just twisted the wires together and covered them with black tape. As I get to them, I am using compression connections of the Ancor heat shrink variety.   John Emmerich 5874 Fortitude Awesome wind the last three Wednesdays (10 to 15) but we keep correcting lower -----Original Message----- From: catalina27-talk@memberclicks.com [mailto:[EMAIL PROTECTED]On Behalf Of Sebastian Cwilich Sent: Saturday, July 08, 2006 2:06 PM To: catalina27-talk@memberclicks.com Subject: catalina27-talk: strange electrical problem and bilge pump advice The other day I was installing instruments on the boat and decided to use the same electrical wiring that lead to the old (SR Mariner) instruments.  The old instruments had more than the 2 wires I needed, and I started using the tester to figure out which were the correct ones.  It SEEMS like in the process I must have shorted something.  I’m not sure exactly how, as it’s a completely different circuit, but my stereo started blinking and then went out altogether, and now I’ve realized it appears that my bilge pump was shorted as well.   SO, my questions are as follows:   -          I have a Rule Mate 750 bilge pump – is there some fuse or something I can try changing, or do I throw it out and buy a new one?  If so, is there some replacement that will fit into the same base to avoid new holes/etc? -          Any thoughts on what might have happened that caused a stereo, NOT on the circuit I was testing to short, WITHOUT even blowing the fuse protecting it in the electrical panel?  Any tests people suggest running to try and figure out what happened?  I realize this is probably not nearly enough information to answer my questions, but thought perhaps there’s some obvious things to try.  Thanks.   Sebastian
