Speaking of doing things the hard way
« on: April 25, 2013, 10:46:43 AM »
I was at Hannays yesterday, got a Johnson ultima auto bilge pump sw out of the bargain bin for $5.
Of corse it did not work :/, so I carefully cut it apart and found the FET that turns the motor on was... Blown open

So I found one I had, that had similar specs (the original one was rated at over 100A and had a vary low "no resistance") but I figured I could get buy with a smaller one as my pump only draws 3A. Soldered it in kinda upside down.

Put a small heat sink on it and glued it in place with 6200 RTV.

Tomorrow when the RTV is cured I will test again, then "solvent weld" the case back together.
And yes... I do understand it would have been easier to just buy the new one for $40

Well Joe, really the only thing you are out is your time. At least you know how to repair things like that.

I wouldn't put a bilge pump in any of my boats that doesn't have an automatic float switch so time well spent IMO.
