Yanmar 3YM30 - Seeking Details on Connectors to Panel

[DevoDave]

Howdy,

I'm creating new replacement engine panels for my two 3YM30 Yanmars. Trouble is the boat is half a continent away and in commercial operation so I need to turn up with a bolt-in solution.

According to the wiring diagram in the manual, there is a three-wire connector in a triangular configuration and an eight-wire connector in 2 rows of four.

A bit of googling suggests that one or both of these connectors may be sourced from Yazaki, but without knowing more detail I am struggling.

Anyone able to provide any more information?

Go to:

Cascade Engine Center | Diesel Engines | Yanmar Manuals

pick up the PDF file engine manual for your engine. It's free and complete, the schematics are in the manual

[DevoDave]

I've got the manual, and the schematic, but it's not too helpful. (thanks though...)

I *COULD* buy the harness from Yanmar, but all I need to know is the OEM connector part numbers.

I just had a look at that service manual, seems very limited, I was looking at valve adjustment- no luck- I would have thought it went into some real detail but thanks for the link anyway- I suppose I need the shop manual -

I just pulled my gauges out for you and took pictures of the only numbers i could see, I hope this works for you!

I'm in Australia so shipping is a killer, and I don't want the OEM panels because they are crappy. I'm making my own with new Faria gauges and Cortuna switchgear. The OEM gauges crack in the sun within a couple of years.

(And what do you mean by 'cheap'? I think I was quoted AU$750 here..)

Thanks heaps for that... appreciate the effort...

However, I'm needing info on the *CONNECTORS* that go back towards the engines. On my panel the wires from the tachos/switches/etc are a couple of feet long and terminate at two connectors... one three way and one eight way. Those connectors are what I need.

Because I have to send a bolt-in replacement half-way across the continent and cannot pull the old one out of service until the new one is ready.

Bump...

Can someone please provide the Yazaki part numbers for the male and female connectors made by YAzaki that Yanmar uses in the harnesses fo rthe YM series engines (Yanmar PN 128391-77720, 128391-77700 and 128990-77920 $180)?

This is to make my own (tinned) harness that will be drop-in compatible with the original one...

Many thanks!
