Everything was fine last night now all of a sudden the main relay doesn't click when you turn the key
I took the relay off and tested for power
Only the yellow with white wire has power
The key being on or off makes no difference

Checked fuses they look good not sure exactly which ones to look at

 

There should be 3 powers...

1- 12V constant, hot at all time.
2- 12V switched, hot in run and start.
3- 12V switched, hot when cranking to start only.

Which one(s) are you missing?

What is the MM&Y of the car? 94

 

Considering that the main relay on these cars are commonly known to fail, it better to start troubleshooting the relay first rather than the wiring.

 

There are a few threads on how to fix them instead of buying new ones. Look them up.

 

Main Relay Fix, Troubleshooting (Honda, Acura) and how to solder

or just buy the mitsuba relay on rockauto or ebay for like 20 clams.

 

No it is not, you need to know if the relay is getting it's powers and ground, that will, in turn, let you know if the problem is the relay.

You are correct, they are a common problem, but checking the relay first is like checking the engine that will not start before checking to see if you have gas and spark. 94

 

Testing a relay isn't significantly laborious than checking power and ground on harness wires.
In fact, it is nearly the same proceedure.

Since we know for fact the main relay is a very common issue then logically you start there.
its logic, my friend.

 

How are you testing the relay if it's missing one of it's powers???

You always check for powers and ground to a load first, take my word for it, been doing auto electric for more then 35 years, my company is FCM Auto Electric. 94

 

Fantastic.
So you must understand how to inject 12v and how to use a voltmeter.

 

"So you must understand how to inject 12v and how to use a voltmeter" nuff said. 94

 

Add the required car information to your post.

Not trying to take sides in the debate. I'm here just to say that the fear of anything electrical is high and irrational on these forums.
