Yam multi function gauge alarms

Quick question. I'm helping a friend sort out the wiring on a 1995 ish V4 130hp.

If the gubbed multi function gauge is disconnected does the buzzer in the remotes still sound if there is a problem?

Also the oil level sender on the engine. .. are thé switches normally open? I.e when the level gets low that bit of the sender makes the connection?

Thank you faries....... Except the 2nd post now won't make sense to anyone!

Don't suppose the Spelling faries happen to be best mates with the Yam V4 self protection mode from the mid 1990s faries?


Back to the original Q -
I have found more..... The Entire oil injection systme has been removed, and the tank level sender's plug has been left floating about i nthe cowl. Now, based on my old Suz, at low oil it self slowed to cool itself down (retarded the spark I think) and at <low low. oil shut itself off.

As the Multifunctio ngauge has good - low - empty LEDs, am I safe in assuming the engine will shut itself down if the "low low" switch is triggered - or, possibly as it's not connected - the saline dampness makes the control module think that? We had a yellow" (low) with it not connected.....

Only found the ops manual o nthe yam website - but nothing about what else alarms do apart form reducing revs to 2K or so..... do they also prevent restart of <low low> is detected?

The multi guage has no effect on the engine running.

When the oil system is fully operational it will cut the revs if oil is low. It will carry on at low revs until the engine seizes up!

If turned off with low oil It will still restart but will only run on low revs

if system is removed the engine runs without producing any warnings. This engine has been run for 20 odd years racing in the old OCR B class with oil systems removed. It should give a very minor hp increase. if the system is removed then I have always turned up a delrin blanking shaft to fill the void where the shaft was in the block as the removal of it causes a slight reduction of crankcase compression on no4.

Phantom,

Thanks. I know the gauge has no effect. It was what the engine did with a low / no oil warning. My old suz did that, except low low oil seemed to prevent a restart.

Also I had no idea how it would like having no signal from any pin on that plug.

On the engine in question the battery state may have accounted for the lack of restart....

More later.
