what year is your magnum?
Manufactured date 08/04 The title says 2005 ser# XXXXX 32AX 5B40 9186
Yes it is a 2005 I am checking the wire diagram
is the thermister #12 disconnected?
Jeff I was just thinking, when the fuel problem occurred I did not know what was the problem so after it quit a couple of times I drained the fuel and put in new fuel I did leave it running here at the house to see what it did after a few minutes it did stop running, that is when i discovered the fuel filter melted. I guess while it was running in the driveway it could have overheated however I am not sure.
I will go out and check #12 back in a couple of minutes
If it did over heat it may have damaged the therister. if you have a ohm meter we can check it
yes # XXXXX is plugged in. If it would have been unplugged the fan would not be running when I start the bike would it?
Yes I have an ohm meter
the fan and hot light would be on if it is disconnected.
sounds like your on to something
using the black/yellow wires from the thermister disconnect the termister and attach the ohm meter leads one to each wire of the thermister and let me know your ohm reading
ok i just got done putting a new battery in my meter back in a couple minutes
jeff with the ohm meter set on 200 it shows .5
I only have one good hand i i have trouble holding everything i thought about putting a little aluminum foil in the plug to help but was afraid it might alter the reading the meter was jumping al over the place because i was having trouble getting good contact however .5 was always the steady reading.
Jeff I stuck some aluminum foil on the contacts and the measurement was the same .5
with the oil temp at 77 deg you should have a rading of 100,000 ohms and go to 1.6000 ohms when the oil is 290 degs. the resistance is way lower than the 290 deg reading the thermister reading about 500 deg from the reading you are giving me. that is not possable. I would start with the thermister but the power control moduel could b bad also.
OK i'll get a new thermister ordered asap. I see where polaris recalled some bikes for a faulty ecm i am going to check with them to see if this is one of them.
I looked for the recall on your unit it does not show as one that has a recall. check with you dealer to make sure
Thanks Jeff I would guess your right on
