Vacuum staying on

[MEP001]

Instead of tying the 10 gauge wires at the timer, pull the bracket out that the timer is attached to and connect a new wire at the terminal strip on the back along with the incoming wires. If there's no strip, connect a new wire to the incoming line and that will go straight to the mercury relay "in" with another wire from the mercury relay "out" straight to the motors (or fuses if it has them). The old timed load that went to the motors will now go to one terminal of the mercury relay of the coil, the other gets a common (white) wire tied into the wire nut already up top.

When you get all done the timer will only control the coil on the relay, the coil only draws about 55 mA so the timer should last a lot longer. Think of the relay as a switch, you put power to the relay coil the coil energizes relay. The Load terminals are designed to take a 6-14 AWG wire. I connect the wires from the vac motors together and then connect the single #10 wire to the relay.

Albeit ... it requires more effort & a bit of modification ... but one of the best things we did was go to Dixmor LED7s for each of our four vacuum timers. Also away from the inside bay water & humidity ... we repurposed some of our "6 distinct coin" IDX's for our vacuums. Pretty much 100% flawless reliability! While the modifier is at it ... Wago wire nuts have their advantages also.

This is what I have but my vacuum will not kick on.

The top wire on the terminal is my hot wire. I checked and it has 125 volts on it.
The second terminal wire goes to my motors.
The top coil is a common tied to the bus bar.
The bottom coil is tied to the timer.

Anybody see what I’m doing wrong?

 

[MEP001]

I don't see a line going into the timer relay.

 

[Noob]

Which one is the timer relay?

 

[MEP001]

The block on the right that sticks out is the timer relay. You need a hot line in to the relay so it can send power out.

Right here?
The empty slot (currently not visible) under the yellow connector.



Also where should I be drawing my power from for that wire? Is the bus bar ok? 10Ga?

 

[MEP001]

It doesn't need a heavy wire since it's only powering the mercury relay coil. It just needs always hot power to that spade terminal.

Got it! Thanks MEP, Randy and others. Couldn’t have done it without you.
