Does it click once or multiple times when trying to start the engine?

Are you looking for some possible causes or would you like me to walk you through this diagnoses?

Customer: replied 12 days ago.
the ccrm clicks multiple times
Expert:  AMEDEE replied 12 days ago.

What is the battery voltage at?

Customer: replied 12 days ago.
12.5
Expert:  AMEDEE replied 12 days ago.

What about under a load when you turn the key to the CRANK position?

Expert:  AMEDEE replied 12 days ago.

It sounds to me like you just have a failed battery. :)

Customer: replied 12 days ago.
actually i charged the battery and it is at 12.7 and when i turn on the key it doesn,t drop. and when i tyrn on the head lights which don,t come on it also does,t drop
Expert:  AMEDEE replied 12 days ago.

It should drop down when there is a load on the battery. If not, maybe you have a bad connection at the battery. This would leave the battery voltage normal (12.7 volts) but cause the entire vehicle to have low voltage.

Check the voltage on the MAIN fuses under the hood.

Customer: replied 12 days ago.
i don't think so i took the terminals off and cleaned them. but i will check. also this happened twice. it was sitting there with the light switch on , n o lights , clicking noises going, then the clicks stopped the lights came on and the car started.
Expert:  AMEDEE replied 12 days ago.

Low voltage is why the CCRM or any relays click like you are describing.

Please check this and let me know.

Customer: replied 12 days ago.
i checked the voltage on the cables going into the fuse box as well as the voltage on two of the fuses and it was 12.3 volts
Expert:  AMEDEE replied 12 days ago.

Is this with the key in the CRANK position UNDER A LOAD?

Customer: replied 12 days ago.
no,there is only me i can't try to crank it and check the voltage. will the on position do.
Expert:  AMEDEE replied 12 days ago.

No, you need to crank it over.

If you are using a meter, you should be able to hook the leads up to the battery and prop it up so you can see the meter while turning the key to the CRANK position.

Customer: replied 12 days ago.
well that is what i did when i checked the battery voltage. i will try it with the fuses but it won't be as easy.
Expert:  AMEDEE replied 12 days ago.

I understand. I have been a mechanic for 15 years.

Would you be willing to speak on the phone?

Customer: replied 12 days ago.
ok the voltage did not drop.
Expert:  AMEDEE replied 12 days ago.

Ok then your next step is to check voltage down at the starter with the key in the CRANK position.

Let me know.
