Arthur - I guess that depends; I have a multimeter, test light, etc., - will these be enough?

Yeah..just basic circuit stuff ..some test leads , jumpers , and the main thing will be a 12v source..like a battery

Pull the relay and I will match up those numbers with the circuits.

Numbers should go from 1-9.
Have a battery?

Arthur - I have two sources of 12 volts; my lawnmower battery or my 12 volt battery charger.

Ok.....use the battery cuz a charger can spike the OVP and the zenier diodes will drop the input.


Take the relay and hold it bottoms-up so you are looking at the pins, with the bottom row being the row that includes the one small pin. Put it in a vice or some holder.

So , the number for each row of pins as they face you , will be :

Bottom row ..L to R
1,3,5
Middle row L to R
2,4,6
Top row
7,8,9 ..L to R

Bring 12 v + to pin 1
Bring 12 v - to pin 5
Alligator clips work well here.

Now , take the test lamp and hook one lead to the battery - [ this lead stays there for all test]
Test pin 1 and 9 with other lamp lead ..lamp should lite.
Now , jumper wire pin 3 to pin 1..that should energize the relays [ there are 3 in the 000-540-67-45] and you should hear them click. If YES,
Test lamp lead at 2,7,and 8. All should lite.

Last test requires ohm meter set to continuity.

With jumper from 3 to 1 still in place , you should have continuity across pins 4 and 6. No voltage on this test , just cont. b/c it is a switch inside the OVP.

When the jumper from 1/3 is removed , all those voltages should go OFF and the cont test at 4/6 should show OPEN.
I do the jumper from 1 to 3 with a screwdriver so I can do it several times while watching my test lamp and meter to make sure they make contact every time.

If any test fail, tell me which.
If none fail, then I will tell you how to do the feed test to the OVP at the socket plug in the car that the relay connects to.

If you do not understand any of this , ask BEFORE you burn something up................
