Step down transformer 120v 12v bad

the wattage is on the plate attached to the drill and will still be the same as before you attach a step down transformer to get to the correct voltage
get a step down transformer that has a large wattage rating for 120 volts ( say 1200 watts ) as most 1/2 drills are 750 -1000 watts )
the wattage is for the rated current through the transformer and if the drill is of low wattage , it just gives the transformer a greater degree of serviceability in the duty cycle

check high voltage going to board and transformer then check low voltage from transformer to board. If you have voltage on these board is bad. Correct voltage that is.high 110v-120v low 24v-28v

This had nothing to do with a BUELL.

Your issue is that the dimmer is not rated to handle the type of fixture/lamps its controlling.

From a lighting control standpoint, the 12V-lamps classify as "low-voltage halogen" and, somewhere in that circuit, have a transformer(s) converting the 120V~ down to 12V~. Using incandescent dimmers (like the one you are using) can cause compatibility issues with those transformers. What I suspect is happening is that the incompatibily is either throwing voltage spikes or current spikes on the line which are causing the dimmer to enter some sort of "safety" mode to shut everything down before any problems occur.

My recommendation is to first figure out what type of transformer it is: Either magnetic low-voltage, or electronic low-voltage. Ideally you would contact the transformer manufacturer (or look up their specs online) to figure that out. Other rules of thumb: if the transformer's big & bulky, it's probably magnetic - conversely if its lightweight, it's probably electronic. If its only one transformer controlling all of the lamps together, it's probably magnetic - conversely if its one of those transformers where the transformer and light bulb come togheter as one assembled unit and then snap into the track, it's probably electronic.

Then make sure the dimmer is rated for magnetic low-voltage, or electronic low-voltage (depending upon what the transformer is).

Sounds like the transformer in your track light. In the box where the green light is, the voltage is converted by a small transformer from 120v to 12v for the halogen lights. With the breaker off, try jumping out the dimmer going to the track light (disconnect the dimmer and connect the two loose wires from box together). With the breaker back on, if you have 120v power on the wires (black/white) going into the track light transformer (measured at the track light), and the green light won't come on, I'd say it's the track light transformer. You may have to replace the whole track if you can't get the transformer as a part.

the switch may be Faulty the fan and light are on parallel circuits.

What does that have to do with a BUELL?

This has nothing to do with a BUELL.

Dimmers should always be connected to line voltage (usually 120 volts). That is, when a dimmer is used to control a low voltage transformer it is always connected between the source of the power and the primary side (the line voltage side; the 120V side) of the transformer; it is never connected to the secondary side (the low voltage side; the 12V or 24V) of the transformer.
