My Q-runner runs good and starts fine,if I use the pull starter. Today I splurged and bought a new battery. I added acid and charged it. It measures 12.16 volts across the terminals. However electric start does not work. I know that I have continuity to run the engine b/c it runs if I crank it by the pull starter. The headlight is still very dim(no juice from the battery). That leaves me to beieve that the battery is in an open loop somewhere.

So I checked the neurtral relay............no good
Then the starter soleniod.....................no good

Then I think,damn, WTF can cause all this. I then figure that to start w/ the pull starter,I must have continuity b/t the kill switch,ignition switch.
So, to use the electric start I must have continuity b/t the 2 above components,plus the starter solenoid,the neutral relay,and the engine start switch. In order for all 5 of these components to have continuity,the FUSE must be in good shape.

Well after all this I checked the fuse and sure enough it was toast(15 Amperes).So I replaced it and that one fried and the next. HELP.

And excess current causes fuses to fry, what would cause the excess current????? I am tired, Later

 

I don't claim to know anything about quadrunners, but I do know electrical stuff can be a pain in the a$$. The only thing I can think of is that you have a wire grounding out or corroded connection somewhere. We had a '92 Timberwolf on the farm that had similar symptoms to what you described, and it ended up being a bad connection. The connection looked fine and tested OK with a continuity tester, but had just enough corrosion to make the starter not work. Could a small arc between a bad connection blow fuses?

 

Well being a Q - runner it has to be somewhat old and with age can come cracking in the insulation of the wires. I would look for a short. If you are blowing fuses that quickly it is most likely a short.

 

Voltage divided by resistance equals current, so if you have to much current, there's not enough resistence (couse the voltage is known), so there's probobly a short somewere in there.
Let us know what you find

 

Hey Bigben, whats your other toy???? jast curious

 

John Deere 6950 forage harvester.

 

Problem solved. The ignition switch was the wrong one. A 68$ part at the dealer fixed it .Thanks for the suggestions here in Bomb country. I do not have a Z400 or vinson so the tips are scarse in the zuki forum,Later.

 

dunesled,my zuki is but 17 yrs young.Old is so harsh,how about "classic"!? Later

 

Sorry about the shot bro, I,m well aware of bikes "that get better with age". I've got a 85' 250R three wheeler that blowws doors on any stocker and looks better too.
