79 Club Car Solenoid

How do the 5 solenoids work?

as you push the go pedal the micro switches engage the Solenoids
the first one (right side of photo) is the main it supplies power to the others
the current flows through the resistor coils to the motor
the resistor coils burn off power making the cart go slower
as each Solenoid is engage it by passes the coils making the cart go faster
with the go pedal fully push the last Solenoid (left side of photo) engages by passing all the coils giving the motor full power

Thanks. Do the solenoids also determine the reverse speed? My reverse is very week.

reverse is hooked up to 18v from the factory
if you want it to go faster (in reverse) i'd have to tell you where the cables go

[rick1985]

Tell me. But only if it won't damage anything.

there is no harm in moving the cable for full power reverse ... just be aware you will go fast backing up

move the wire on the #4 neg battery to the #1 positive battery post
i know this sound strange but they used the #4 battery to save cable
this is a close diagram of your set up
red cable is the one to be moved

Thank you. One last question. How do I test the solenoids to see if all are working ?

solenoid test

Disconnect the negative battery cable from the battery. remove all wires, restorer , and diode from solenoid
test 1
Connect a volt meter, set on continuity, place on the two large terminal studs. The meter should indicate no continuity, Replace the solenoid if continuity is present.
test 2
Using jumper wires attach from main positive and main negative of battery pack to the two small solenoid studs, polarity is not important. You should hear a click as the solenoid engages, and the meter should indicate continuity on the two large terminals. Replace the solenoid if continuity is not present.
if solenoid clicks rapidly solenoid is bad

Once again thank you. I plan to do all of this to get the cart working at 100%.
