Anyone have a source for the 24 volt relays for the upper steering bay?

Tom,

I have successfully used Allied Electronics, www.alliedelec.com (http://www.alliedelec.com/), lately. They are located in Dallas, Texas, so if I order before 7:00pm, I get the parts the next day, using ground shipping. They have a good electronic catalog.



So it works for me.

Tom,

Take a look at the Allied catalog, page 1079. A supply of 12 and 24 volt, SPST and SPST relays.

I purchased a batch of 12 volt relays to interface the ECC and replace the Weshaven generator controls.

It looks like that relay is no longer available, here is a page with recommended substitutes.

Thanks guys, I was able to find a replacement for the old relay number at Steve's source. I couldn't find these locally, so you might want to have a few in stock.

In case anyone is on the road and a critical relay such as Tom posted has puked, look at similar relays, and find one whose circuit is not critical and switch.

As an example relay #76 (I think the number is correct) lights the tail lights when the jake or retarder is on and you are decellerating. You could pull that one and use if for a similar relay that has failed. It still allows your brake lights to function when you apply the brakes.

There are other relays whose purpose you can temporarily live without.

But the real solution is to carry spares because nothing ever fails in your garage, but things always fail when you are far from home and in a town without a parts store.

I think there are other sources for our relays such as Bosch.

I thought the bus was possessed!:( All of a sudden, the marker lights came on and wouldn't turn off. The only way to kill them was the cutoff in the engine compartment. Like Jon suggested, I just swaped out the relay with another and presto, all is good until I get the new ones.

Take a look at what you have and get some spars like Jon said, you'll have both 12 and 24 with different amp ratings and configurations. I had plenty of spare 12's, but no 24's.

Tom, I found them at a Volvo truck parts counter.
