I have found one flaw. I used a normally open relay and I should have use a normally closed relay. With the normally open relay it defaults to high if the power goes out and you run on battery backup. Changing this to normally closed will make it default to low speed on power loss.
BTW: I have modded both my pumps now and both are running great.
For clarity, could you post a part number for the other relay from Rad Shack? Thanks.
Nice mod too.
