Starter Relay

[Armada]

Is the CUCV starter relay (under the dash), the same as a 6.2 civilian truck starter relay? Voltage, etc.?

No, a civvy truck does not have such a relay. Napa relay # AR-135 (search the forums, you will find more than you ever wanted to know about this relay)

Its actually a 12v heater/AC relay

Thanks Mike. I saw that number and printed the thread off, but thought the local dealership might carry the starter relay if the voltage was the same. So the military uses a 12v relay? Napa is quite a bit farther from me, but I'll call them to see if they have it in stock. So why don't the civy trucks have that starter relay?
Most everything else is the same. Do they use something different ?

Autozone carries a relay that works too. As well as others I am sure. Just have them cross the #.

the relay basically switches the 12v start signal to 24v for the starter.

AutoZone it's GP40.

 

[Armada]

The local Autozoo had no clue as to what a GP40 was..... and no cross to a Napa AR135.
Went to Carquest and they had no cross for a GP40 either, but gave them the Napa # and it crosses to their p/n RY117. It mounts a little different and there is an extra prong on it, but it fits the connector on the m1009 and starts the vehicle. I also ordered the OEM relay from FLM.

For future info... There are a VAST number of relays out there that will fit / replace a AR135... They are also made in 40 and 50 amp versions which would prolly be a better replacment for that application.

 

[mangus580]

You are correct on the amps d-man!

Bah ... sorry, AutoZones number is AC40 (GP Sorensen).

You can also get auto relays from Radioshack. I may have one on my junkvee for you Paul. I will check tomarrow. When I was cutting my dash for my radio I thought I had cut into wires because the starter engaged and was turning the engine over. When I stopped cutting it stopped turning over until I started again. The relay is just under the opening for the radio and the vibration of the air rip saw was making the relay make contact.

RE: Re: RE: Starter Relay

I got to thinking about this. I think it is the same relay used elsewhere in the truck. I think it is the same relay as the horn relay. I will take a look tommarow to confirm this. If this is the case just get a horn relay.

The starter relay is different Chuck. There are a number of the same Bosch relays that are used for other cicuits, and they are mounted on the same bracket.
This is what the aftermarket starter relay looks like. There are 2 failures for these. Not working, and stuck on. So if your starter runs off on its own, unplug this or the batteries.

 

[ida34]

I have yet to be able to check the junkvee. I got detained this morning. I will check for you tommarow or Saturday at the latest.

Are there 4 or 5 wires ran to that from the harness?... One is left blank in the plug yes?

 

[Armada]

Yes. There are only 4 wires on the harness, and 4 terminals on the OEM relay. The 5 pin aftermarket relay does plug into the harness though, and it works.

 

[ida34]

I am pretty sure the other terminal you are not using is for a normally closed position.
