How to Test

Got a question, i have a volt meter need to know how to go about checking the stator and/or rectifier on the bike.

the battery sometimes stays charge, sometimes wont. i have a spare at the house that is good.

when rolling hard on the throttle the gauges will reset, sometimes the needle on the rpms wont reset when turning on...sometimes its fine

would rather get it sorted then ride it and having it cut off

i know with a car you can just take the positive (or is it negative) lead off the battery, if it keeps running...then battery is bad, if it stops then bad charging. can i do this with the bike?

The gauges go blank and reset? Lose power all together?

Red to positive, black to ground for general voltage check. The bike at idle should be able to sustain min 12.5-6V; around the charge of 13v depending on bike over 1500rpms.

If your cluster has an overvoltage protection; maybe that's what's your seeing if the voltage is spiking. If your dvom has a range min/max, activate it, roll the throttle hard and see if the max is over 15...

Find the regulator box, check the A/C wires(sometimes white, there will be three of them) and check on AC setting on the DVOM one at a time. For actual spec, consult repair manual; otherwise I have seen 180(dont recall if it was V or kV) from each wire.

If the arent to spec; you need to check the stator. If they are to spec then inspect the regulator for failure to convert the AC to DC voltage properly. Voltage drop checks from the battery post to the cable can be done as well to make sure the battery voltage is not lost through parasitic reasons/poor contacts.

Motorcycles Unlimited does a great job diagnosing these issues and knowing the systems proficiently.

2 part question. first part. some cars you can now some cars u cant. 2. no u cant do it on a bike.

stator check: unplug R/R measure ACV from stator (3wires all the same color) should be at least 50ACV revved up. check it between all terminal ie: 1 and 2, 1 and 3, 2 and 3.
only thing left is the R/R with that IIRC u check via diode setting should be around 0.5 (been a while since i read up on it so dont hold me to it) polarity matters on this one. GL and LMK

Sounds like a bad voltage regulator to me.

REGULATED VOLTAGE

Start the engine and keep it running at 5 000 r/min with the
dimmer switch turned HI position.
Measure the DC voltage between the + and - battery terminals
using the multi-circuit tester. If the voltage is not within
the specified value, inspect the generator and regulator/rectifier.
(9-10 and -11)
NOTE:
When making this test, be sure that the battery is in fully-charged
condition.
Regulated voltage (Charging output):
14.0 15.5 V at 5 000 r/min

GENERATOR COIL RESISTANCE

Disconnect the generator coupler.
Measure the resistance between the three lead wires.
If the resistance is out of specified value, replace the stator
with a new one. Also, check that the generator core is insulated
properly.
Generator coil resistance: 0.2 0.9 Ω (White White)
∞ Ω (White Ground)

ELECTRICAL SYSTEM 9-11
GENERATOR NO-LOAD PERFORMANCE

Disconnect the generator coupler.
Start the engine and keep it running at 5 000 r/min.
Using the multi-circuit tester, measure the voltage between
three lead wires.
If the tester reads under the specified value, replace the generator
with a new one.

Generator no-load performance:
65 V (AC) and more at 5 000 r/min (When engine is cold)

sweet

this should be stickied, after re reading, is this saying to test 3 wires at once? sorry i know i sound stupid. but id rather ask then going to the garage spinning them together and testing them

no, test each one of the three leads vs each other then test each lead vs ground
