Oil from reservoir to cowling yamaha motor 200hp

[wonderous]

Hi there

Had the motor serviced and ask mechanic to check the oil as the alarm
was sounding.
He put another oil pump in and later discovered that was not the problem.

He seems to think now that is the wiring. It now tells me he is guessing.

We checked under the cowling and oil tank was half full.
The oil reservoir is full but its not feeding thru to the cowling.
Are you able to assist.
Thanks

oil level warning sounds

I just repaired a similar problem. It is a wiring break from motor to sub tank on boat. You can do a ohm meter check from inside motor connector to sub tank on all 4 wires. I found fuel line deteriating and leaking inside 3 inch tube connecting motor to boat. Fuel attacked insulation on all wiring and battery cables inside tube. Had to cut off tube because of insulation swelling. Hope this helps

fuel has nothing to do with oil.
ya need an alternator.
had it serviced cause an alarm???
no you had an alarm and hoped a service would correct it, it wont.
you do realize there are two oil tanks and 4 switchs in the system?
and as we still dont have a model number no one knows which system you have.

oil supply problem

if fuel detiorates hose and leaks on wiring inside of casing causing insulation breakdown and wiring corrosion , then I would say it would affect oil supply.Then they would be related!
