Having problems with your Broan-NuTone CV750 Central Vacuum ?

Low voltage wiring

\015 My vacuum wouldnt shut off so i replaced the relay. now the vacuum shuts off but my outlets dont work\015

Answers :

Probably just didn't wire the l/v side of the relay properly. Or forgot to plug the leads from the outlets back in to the vac after you got it all hooked back up. Folks do it to me all the time and then make like it's my fault! Ha ha.

Jump the l/v contacts inside the CV. If it goes: trace outward toward the outlets to see if something shook loose while it was apart. If you can't jump the l/v with a plier/screwdriver at the CV or even inside it, you have an issue on the board (either how you've connected to it or it's defective itself). The prob is that there's dozens of diff board configs, plus the relays and transformers weren't together on the same board in the old days. If you've got one of these models with a massive transformer separate from the relays get out the test leads and make sure you've got adequate voltage coming out of her to power the relay coil.
