[bigmudder]

hi iam new here but i have a 08 750 king quad and at idel it charges and when u rev it up it does but when u turn the head lights on it does not and the regulator gets hot. the battery is good and its a new regulator..some say stator but before i buy one for 200 dollars i would like to no if that is it or not and how do i test it .any help would be great thx dan.

here is the service manual, i think it has the specs to test the volts/ohms etc. for troubleshooting.

it could be a bad ground, a couple wires touching and shorting out and could be the stator too ... tough call ...

thank you

i ran the test on the stator and it check out good.i added a few grounds and it actually bump up my volts from 13.50 to 14.53.and when u turn the lights on it charges now. but after 15 to 20 mins. the regulator gets hot it quits charging and iam assuming thats what it is doing.and wont charge anymore.but if u shut off the fourwheeler and start it back up it will charge again until it gets hot.do u think its the regulator or not. i could use some help here. thx.

the regulators do get very hot during operation, very hot to the touch ... you could cook an egg on it, but not light a cigarette ... i would hate to see you spend money on something you might not need. do you have a buddy with the same bike you could swap the part out to check? i know electrical components are non returnable/refundable after the package is opened ...

[bigmudder]

no i dont thats the bad deal.i dont mind spending a 100 bucks on it if it would fix it. but like u said your out your money if not.

[bigmudder]

and does the regulator kick in and out or no.

[oxidized_black]

im pretty sure it runs all the time, leveling out the current ...

it almost sounds like the stator is failing because thats what makes the power, but then you wouldnt have spark to keep it running ... im not sure what other modules are in between ... so maybe it is the regulator, does the current drop and/or spike with it running? i think it should be 14.5-14.7 ???

[bigmudder]

it dropes.

[oxidized_black]

if it were me, i think i would gamble on the regulator then ... it shouldnt drop or spike ...

[bigmudder]

i had several people say check the grounds i think i checked all the grounds and added a few. i just dont no what to do.

[bigmudder]

thx for your help. i may have to buy one.

i was hoping a member here, XWrench3, might have jumped in on this thread ... maybe send him an internal mail from here and ask if he would read the thread and give an opinion ... he has been dealing with Suzuki all of his career

[bigmudder]

ok i sent him a message i hope he can shed a little light on the subject. thx again

[oxidized_black]
