Cannot find replacement Volvo Penta 4 terminal tilt relay

[NB2]

I have a AQ240 engine with a 280 drive. I need to replace a tilt relay. I have two relays, one is a five terminal and one is a four terminal. I need to replace the four terminal relay. I can find many five terminal replacements online but am having no luck finding the four terminal one. I have searched and contacted tech support at various vendors but am still having no luck. I think I have an early 280 drive unit on my boat. Relay is a 12V 30 amp.

Just use a five terminal, n leave and insulate the spare

If you can either post a picture of the relay your are looking for or know enough about how it is wired, you can replace it with most any type that has the same function and current carrying capability. But then you also have to rewire for whatever relay you select. But some times that is the better way to fix things when replacement parts are not available... JMHO

its a standard 12 volt, sealed VF4 style relay (probably with diode supression) available nearly anywhere. I buy mine online from either newark or digikey.

the 4-terminal relays simply do not have the NC terminal. in theory, it saved the OEM about $0.10 each.

If I may add one important thing. Be very careful which relay you buy. Even two relays with the exact same layout and size and even looks can be different. I learned that recently the hard way when trouble-shooting my neighbor's RV air conditioning system. He had a suspect bad relay. I had an identical "looking" relay laying around the shop and gave it to him as a replacement. His air conditioner still would turn on and run properly. So with the schematic diagram and a multimeter, I set out to figure out why. And I finally got down to the relay. And it kept puzzling me that the relay was not functioning correctly. And I knew for positive the relay was absolutely good. And finally I remove it and did a serious check against another same looking relay. WALA, two relays with the same looks and pinouts with totally different functions...who would have thought... So just be forewarned. On some of those seemingly simple relays that are available everywhere, the contacts don't function the same way. One has a wiper that makes contact when energized and breaks from the original contact, while the other makes when energized but doesn't break from the original contact thereby having the two contacts connected together at the same time when energized. And this was verified by opening up the relay itself for curiosity. So use a meter to make sure you get what you want...

Took some photos of the relay today hope that helps with identification. Here they are.

see post #4.

take a pic of the schematic printed on the relay. it will tell you if it is resistor supressed or diode supressed.
