NO MORE CLICK click CLICK START..ONLY START! starter relay

SomethingElse · #1 09-29-2009, 08:26 PM

Well it finally happened to me..click click click yadda yadda yadda why wont this ****ing car start!.....after tracing the wiring diagram and drawing out the circuit I began to do a simple voltage drop test in the most conspicuous area....THE INHIBITOR RELAY!!! GUESS WHAT!!! BAD INTERNAL CONTACTS...VOLTAGE DROP!!!

Ok sorry I got a little CAPS happy

replace relay...start start start start start

US models only, so our non us members with non us spec SVXii could not assist....we suck..before adding relays do yourself a favor and replace the bad one first.

Inhibitor relay + inhibits starting = fail.

How about a little help for the lazy amongst us??

Where abouts?
Pics of the bastard?

SomethingElse · #3 09-29-2009, 08:49 PM

Mine was hanging under the dash... it may be attached to your steering colum..its a black box relay attached to a harness with 4 pins (connecting to a 5 pin relay as young buck Tom found out the hard way).

wiring diagram calls it starter inturupt relay adapter

I will can take pics tommorrow I need to fix the mess I made...sorry its late

do show and tell!!

Its the only black relay under the driver's side dash... I will give it a go sometime as my car had serious starting issues before the relay mod. Will be a good test bed to confirm

Cool find! Relay mod be gun?

Can it start cars that ran out of gas too?

Good one Eric.

Hoooooray, at long long last someone has had the brains to trace the problem.

I have always suspected the inhibit relay because it is a normally closed device. This means that the contacts are closed by only spring pressure and also have limited over travel. As a result they are more prone to give trouble, than normally open contacts.

As I keep pointing out, a fault of this sort left existing, could in future result in a completely open circuit. In which case a slave relay will not overcome the problem. Be very sure it will happen on a wet dark night, a long way from assistance.

Cheers , Trevor.

One question:

is it a standardized part, or is it a subaru or SVX specific module.

Part number or specification, as well as location would be helpful. I need to replace my steering column shroud covers anyway...

Ill do my best to do a quick write up by lunch time, with pics and part #.

And hopfully by this weekend, Ill write up a how-to no start diagnositic flow chart.

Good one Eric.

The complete start initiate circuit is not on record and this will be of real value. The inhibitor switch, security system and starter interrupt relay are also niggers in the wood pile.

How about breaking open the faulty relay and advising what you find. Return spring pressure weak, obstruction in the armature return, or whatever. You are the first to properly diagnose the fault, so might as well go the full distance.

Cheers, Trevor.

Already planned to

, im pulling it apart as soon as i get to work...i suspect ill find the contacts melted, corroded, and deformed on the secondary half as ive seen before on other bad relays.

SomethingElse · #12 09-30-2009, 06:01 AM

got to work..opened it up..sure enough...the spring was slightly deformed causing it to only make contact in one small area...after years of being abused in one spot it began to develope craters

Its just a plain relay the same one used for the band-aid fix 12v 20/30 amps

and the contacts inside the relay...

Looks like I know what Ill be doing to the Ebony this weekend!

SomethingElse · #14 09-30-2009, 11:22 AM

running 15 or so starts strong

took it out to lunch and ran some errands..

I even stalled my car on purpose a couple times just to hear the sweet goodness of starter solenoid engaugement on the first try

major7venth · #15 09-30-2009, 02:20 PM

Question, did it act as if it had a bad starter solenoid? click, no starter turn?
