Can someone explain how to check to find out which solenoid is bad? All I am getting when I hit the back switch is the solenoids clicking. The pump motor does not come on. I already changed the pump motor so it can't be that....what else could it be? Any help would be appreciated...thanks

Low batts, bad connection, bad ground.....

The Science of Hydraulic Suspension

You need a continuity tester.
Probe on either side of each solenoid and have someone tap the switch for you.

If it BEEBS before tapping the switch = STUCK CLOSED/BAD
if it never beebs = STUCK OPEN/BAD
If it only beebs when you tap the switch = GOOD

It only takes one stuck open noid to stop the electricity from flowing to your motors.

"Beebs" = :roflmao:


Anyways......going off of this statement "Probe on either side of each solenoid and have someone tap the switch for you. "

Are you referrring to testing all three noids in a series. Another words putting one probe on the noid on the far right, and the other probe on the far left OR one probe on the S and one probe on the I and testing them individually?

yeah beebs -- lol..... hahahahahaha
EACH SOLENOID, one at a time, not all three together.

if electricity flows through, the tester will BEEB (or light up), if electricity cannot flow all the way through because one solenoid is bad, then the motor can't spin
:biggrin:

:cool: :cool:


I thought that's what you meant but it's early and I might have been off track

Thanks fellas I'll check it out when I get home from work. I don't think it's a bad ground or battery, the front is wtill working fine and it's hooked up six batteries in series. I just couldn't remember how to test the solenoids..that's what it has to be.

Its also a good idea to periodically check to see if one or more of the noids gets stuck as NC (Normally Closed). Typically, they are NO (Normally Open) meaning that hitting the switch causes them to close and connect batt power to the motor. But, you will notice 1 or 2 sometimes will get stuck CLOSED (mechanically, not electrically) and you'll be basically running off of 1 of the 3 in series, then its time to swap a few out :)

You do this test by simply checking continuity accross the noid being tested, it should be open.

Okay here's the deal....I jumped the solenoids and when I connected the two on the right the motor started spinning. When I hooked up the two on the left it just clicked...this means that the far left one is the bad solenoid...right??
