two stroke oil pump issue

[Valiant12]

Hello: I have twin 225 HP Yamaha engines 2 stroke (L225TXRX)on a 27’ Grady White. When the oil level gauge/float is calling for oil to be pumped to the engine reservoir nothing is happening. I’ve tested the float switch and it’s working as it should and the over-ride switch also works to fill the reservoir. The problem appears to be between the oil float sensor located on the engine reservoir and the Oil Sub Tank Pump. I’ve been looking at the schematics that you have on your website to see what components that are between these locations to see what might not be working but I’m having trouble finding the proper layout. Can you assist me?

Check the wiring and connector to the transfer pump for corrosion. Could also be a bad ground.

If remote tank level switch does not see the proper level , the auto transfer will not work.
Could be bad switch or wiring to or from it
