I bought the Crest TruSweep ultrasonic cleaner..used. Heater works but the ultrasonic doesn't run...had one loose wire and can't find a wiring diagram....

you need test the switch for diry or open. some loose wiring , or motor vibrator faulty. use the multimeter
God bless you

You can wire one up directly to your battery from the pos and neg. I've got 3 wired up in my truck. I've also got a converter wired up to my battery.

check wire on stater

PROBLEM IN THE DASH CLUSTER.REMOVE CLUSTER LOOK FOR LOOSE GROUND WIRE SHAKE WIRES SEE IF DASH LIGHT COMES ON.IF WIRES LOOK OKAY.PROBLEM IS DASH CLUSTER CIRCUIT BOARD ITS SHORT OUT.CLUSTER HAS TO BE REPLACED.

Sounds like you lost power to the timer. Look in your electric panel for a tripped breaker. Turn it OFF then back ON.

Hi, if it's intermittent, it is not serious. First check the plugs and change them if needed. If not the plugs, other possible causes are the ignition wire and a dirty injector. Run a can of injector cleaner thru the tank and if the problem continues replace the ignition wires. If it still doesn't resolve, I would replace the #3 injector. For more info on the code, please see my tip at http://www.fixya.com/cars/r6715318-causes_gasoline_engine_misfires. Please let me know if you have questions, and thanks for using FixYa.

First of all the 70 volt line is used when we are dragging long lengths of speaker wires. hence to counter the drop we use a high voltage line brring it further down without any remarkable drop and use a step down matching transformer to power the speaker according to the impedance of the speaker to the secondary of the transformer. Connect the 70 volt to the 70 volt output in the amplifier. Now connect the other end of the wires tto the primary of the 70 volt transformer. Use the secondary output to connect to the speaker using the tap most suitable..2, 4,6,8 ohms . Check the phasing when you connect or reverse if the bass quality is less.
Hope this helps. Good day

Try calling 1-866-876-4332 ext 224 for tech help, it worked for me.  I only needed a temp
setting/off switch to fix mine.
