3.
Use a voltmeter and measure across the red and black wire while
unit on and you should have throttle supply voltage of 5vdc.
4.
Slide your probe ends in where the wires go into the connector.
5.
Leave the black probe on black wire and move red probe to green
wire and by varying the throttle the voltage should change from .2-
4.9vdc approx.
6.
If no voltage recheck your bypass.
7.
Then move on the 2 wire ignition connector, place black probe on
main large black power wire (-) by sliding it up the rubber sleeve on
the connector to hold there.
8.
Measure both sides of the ignition 2 wires, one should be +48 all
the time and the other on only 48vdc when the key switch is on. If
not, replace the switch.
9.
Check both sides of breaker while black probe left on the black wire
and both sides of breaker will have 48 and breaker off and 0 on
output of breaker.
10.
Move the probes to the motor wire connectors and slide up the
rubbers, and test if you see voltage on meter but no motor then the
armatures need to be removed and put back in, they are stuck.
How To Check Charger Output
Tools Needed – Multi-meter set to DC voltage
1.
Determine the total DC voltage output of your scooter and set the
multi-meter above that amount.
2.
Plug the charger into a 110v outlet, but do not plug it into the
scooter.
3.
Place the multi-meter probes into the holes to the left and right of
the indented key on the charger output side (connector that goes to
the scooter).
****Attention: Do Not allow the two probes to touch each other while in
the charger socket as it may cause a short and/or spark.
4.
This will give you the charger output reading to compare with what
your scooter requires.
