Well, my luck ran out.
Happened to look at the pool this morning before leaving for my last day of work before a 10 day out of town vacation and noticed more stuff floating that usual.
Checked the pad and found the timer not working and pump would not turn on. Figured out that the round fuse on 1 leg of the power had blown. Had a spare and when I turned the pump on saw sparks shooting out the back![Shock :shock: :shock:](/images/smilies/icon_eek.gif)
Realized I had an old motor from my last house that would fit and hopefully would be able to limp through vacation, but could not remember why I had replaced it at the last house. Burnt motor was a 2.2 SFHP AO Smith and my "spare" is a 2.5 SFHP Super II ... having learned here that I should be OK with the oversized pump on the smaller impeller, I thought this could work. Proceeded to take the bad motor off the pump and found a melted area in the rear that looks like it used to be the knob to select 120/140 (see pic ... assuming this motor is DEAD).

Put the Harward motor on (with same seals as I did not care if it leaked for a few weeks) wired it up, wife brought some more fuses home, screwed them in, threw the switch ... a little humming and another blown fuse. Pulled the 2 capacitors and both test OK {starter registered 38 MFD and label says 36-43 MFD; large one registered 23 MFD and I think the label says 25 MFD}. Put them back in, last new fuse, throw the switch, humming and the motor was turning (not full speed, but was starting to prime) ... pop the fuse again after only a few seconds. :x
The old fuse never blew, but the new ones did. Old is Type S, SL 15 amp, the new ones also had a D on them.
The motor spins freely by hand.
Questions:
Do you agree the Caps seem good?
Do you think we just had the wrong fuse and that is why they blew?
Or is there an internal problem with the Hayward motor (bad insulation?) that is resulting in the blown fuses?
Any chance on me getting this pump running tonight ... no time left? Or am I just going to have to order a new pump, let the pool sit for 1-2 weeks until we get back and can install the new one?
Or course I was planning to be VERY busy at work today, and now I have already lost half the day messing with the pool ... ah vacations are so relaxing![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
