I think maybe you meant "....that they do not need to look...", but I get your point. Nowhere in the manual for my pump did it mention that periodic inspection of the brushes was required, and replacement brushes are not listed in the spare parts list. I called March and 3 distributors when...

No, the old pump is trash. The commutator is too deeply gouged to be turned down on a lathe. Absent the debris (and brushes), the motor spins freely. I have no idea what interlocks you're talking about.

Sounds good; I'll look into that. I've got the BR brass pump head and an 809-058-10 polysulfone front housing. Thanks for the help.

Thanks, Walter, for that explanation, which nobody was able to provide to me previously. I don't know my motor's manufacturer -- all I have is the March p/n 0809-0102-1300, and a date sticker of 15/03/06. It claims to be a 24V motor, and the peak open-circuit voltage of the solar panel claims to...
