Ultra 150 voltage regulator Help!!!

[btldigger]

Ok im officialy stumped. Started getting a low voltage warning, checked regulator and it was bad. My box was water damaged so I got a used relay box and changed it out problem went away. Went back out yesterday and started getting the low voltage light again. I pulled a known good one from a buddies ski problem goes away. If I check all 3 regulators they all check good by the manual. But only the one from the buddies ski works. Output from the mag checks good. Anybody got an idea???

Loose/dirty connections?

I got two bad stators one time on my old 93' 750 stand up. Try a new one would be my only guess.

Went through all the connections everything was fine. Checked the stator output and it was rite by the book. I guess it could have just been bad luck to pop 2. The first one sat soaking in water for awhile and one of the pins to the starter relay corroded off so I had bypassed it. When I got the replacement box it looked new inside.

if u are using ohms as the test, throw those away
obvious u have a meter
what a bout a DVA?

easiest and best way to check if bad volt-reg
turn meter on a/c
start motor
put the leads of meter on battery
if you read more than .8V A/C
you have a bad regulator

I just pulled a good one from my 2001, let me know if you need it.

Yep I got 3 meters 2 dvm and 1 analog. The digitals give flaky readings when testing some things. I havent tried looking for ac across the battery.

U need a DVA to test voltage from the charging coil

[btldigger]

Both my digital meters will do that one is a fluke 79 the other is a fluke 87. The charging coil output was within spec but I am thinking about changing the stator out just to eliminate it.

U do not have a DVA
u have a DVM
