2001 SP400

Already got a new battery.

Voltage reading drops off after quad is running. Eventually fans, lights, AWD die.

Quad has been through heck. Well maintained but a rough life. Can't blame it for needing this fix. Magneto system new to me. What is replacement cost? Where do i find replacement instructions? While i'm doing this...Are there upgrades? (could always use more juice)

 

Check that regulator/rectifier located at very front of machine has all 4 wires connected(sometimes one or more can pull loose) should have yellow,yel/brn,red(main power wire) brown. Could be cause of charging problem. Good luck

 

Thanks for the reply..

Where is this regulator located? Under front hood near radiator fill cap???

 

In front of radiator on left side behind bumper guard towards top.

 

OPT,

Thanks a ton. U were 100% correct. One of the wires was corroded and broke loose. Ten min with a solder gun and some shrink tubing and I had the machine charging at 14.5 like its supposed to. U saved me tons of $$$. Can't begin to tell ya how much i appreciate the help.
