My Nissan urban keeps overheating after it got overheated what could be the cause


Cooling fans not turning on, check to make sure the cooling fans are running when overheating occurs. Not enough coolant in the cooling system, check the coolant reservoir make sure the coolant is at at the maximum level when combustion engine is completely cool,if your coolant is low add coolant to the maximum level. (1)Start combustion engine, let it warm up but not over heat. Turn off combustion engine, when it cools completely the coolant reservoirs level will be lower . Add more coolant and keep repeating (1) until the coolant level stays the same after combustion engine completely cools down.Sensor that tells the cooling fans to turn on defective. Non functioning thermostat. Broken impeller inside Water Pump. Clogged radiator. Clogged water jackets in combustion engine. Broken drive belt. Radiator has something blocking the cooling fins(possibly a plastic bag that went against the cooling fins when driving)

Jet table saw 3hp, low torque! New saw, correct electrical hook up, but not much power at the blade, so yes it runs but no torque! mag switch in test position, does it need to be in auto???


I am not sure what model you have but they have this saw in two models one is 230 volt only the other is 230/460 volt.
But that is not a 220 volt circuit. 220 volt is single phase where the 230/460 is a 3 phase circuit.
Look on your motor and see what the power requirement is.
if you have a different machine then the one I am looking at I would switch over to the auto function.

T-30 wiring changing from 460 volts to 230 volt 3 phase


There are several items that will need to be changed or replaced. First rewire motor. Remove weather head cover. On the motor will be a tag that shows how to wire for 460 volts and 230 volts.Check the tag and present wiring to make sure they match. Then look at the 230 wiring and change wiring per motor tag. Again check the motor tag to see max amps at 460 volts and 230 volts. 230 volts will be higher than 460 volts. Check the starter (if so equiped) to see how many amps its rated for. You will probably have to replace the starter. Make sure it has a 230 volt coil. Next size the overload heaters for your amperage. This conversion is not a simple task unless you're familiar with electrical . Good luck!!!
Next the starter coil will need to be replaced with a 230 volt coil

My Rheem Air Handler runs all the time,a/c works fine and cools the house but I want the air handler to kick off when not in use. It's model RBHA-14J00NFRA Volts 208/240VAC PH/HZ 1/60


IS your thermostat set to automatic on the fan switch? If so then you may have a stuck fan relay in the air handler. If it has an electronic control board the relay is on the board and the whole board would need replaced. If it is not a stuck relay then you could have a crossed wire from the thermostat to the air handle, usually the green wire from the t-stat, it could be crossed with the red wire that supplies 24 volts to the t-stat.

Runs ccw needs to run cw hp 5 460 v hz60 wired motor for high volts last 3 wires are orange that went to no.2fc yellow went to no.3 black wire went to no.1


Look you are putting to much thought in to this. To reverse the direction of a 460 volt motor simply swap two of your power feed leads. You know the L1, L2, and L3 simply change L1 with L2 and your direction will change, calm down and do not over think this.

Can i use this on 460 volts


460 volts is the measurement of 2 legs of power, this solid state timer appears to be for just one leg. You would have to check the voltage of 1 leg to ground or neutral and see if control can take that amount. If not you would need a stepdown transformer to use it.
