If a resistor is used in the brake system, it must be set at zero or
bypassed completely to obtain the maximum amperage reading.
Individual amperage draw
can be measured by
inserting the ammeter in
the line at the magnet
you want to check.
Disconnect one of the
magnet lead wire
connectors and attach
the ammeter between the
two wires. Make sure that
the wires are properly
reconnected and sealed after testing is completed.
The most common electrical problem is low or no voltage and
amperage at the brakes. Common causes of this condition are:
1. Poor electrical connections
2. Open circuits
3. Insufficient wire size
4. Broken wires
5. Blown fuses (fusing of brakes is not recommended)
6. Improperly functioning controllers or resistors
Another common electrical problem is shorted or partially shorted
circuits (indicated by abnormally high system amperage).
