Sometimes our engine won't turn over - no power getting to the starter. I think we've determined it's a faulty relay. I'm looking for a replacement, but getting the exact part number is impossible. How important is getting that number bang on, and what do the numbers mean? Pic attached.

Re: Relay switch
The "332014 150" would be the BOSCH part number. It's a 12V relay capable of 30 Amps.
You can probably use a bunch of similar relays in it's place, if you can't find an exact replacement. There are more numbers on the side that show the contacts, but I can't read them from that pic. The big difference in a replacement might mean the mounting method. Looks like the mounting tab is broken off yours.

Re: Relay switch
Also check the key switch itself, they can fail.

Re: Relay switch
Those are common relays but you'll need to check if it's a 4 or 5 pin and make sure you get a 30 amp one. Post the engine serial number

The numbers on the side are just a schematic I believe. (pic attached)

Good thought, but that was replaced last year. Although I am going to get another as a backup and to eliminate that possibility if it's not the relay.

Re: Relay switch
Have you checked power to the relay when it fails ?
The above is strictly my opinion.
