i have a 2005 polaris atp , it has no power whatsoever when you turn on the switch the battery has 12.8 volts and you can short the solenoid and it will turn over but wont start ,the switch ohm'ed fine its getting 12.8 volts to the ecm and only 3.7 volts to the switch any ideas?

 

check the ground on the engine make sure tight and clean. and check connections.

 

ive checked the ground there and under the "hood" they are good ,switches are good ,ohm'ed wires from switch to left switch back to ecm then to 4x4 switch, ive checked those two fuse links im currently on my way towards the stator checking wires. i think my problem might be my ecm .but i dont want to buy one till im shure or at least have a good idea that thats what it is ! is there any way to check the ecm THANKS!!

 

If it uses the same ecm as the four weelers then it could be a ecm and under recall.

 

do you have a dva meter. you can check your voltages running or cranking this is alot better than ohms. i would start by checking dva at the stator, triggers, and than go to the coil. go to your polaris dealer and gat the dva specs.

 

THIS THING does nothing at all ,it has no power to anything when you turn the switch on ,no lights, no guages, no turning over ,nothing its like the battery is completely dead or gone .but its not it, has 12 volts and you can short the solenoid and it will spin over but not crank. i did find 12 volts going to the ecm and only 3.7at the switch ...turn the key and nothing and i checked the switch and its good

 

see if key switch is getting power and get a wiring diagram so you can see the and the ground wires and chase the wires with test light and volt meter.do you have a shut off switch on handle bar and a key switch. If so check and make sure both switchs is on.

 

is 3.7 volts enough at the switch and yes the handle bar switch is on

 

no it is not you should have 12 volts

 

does that sound like a bad ecm to you
