No ignition power to Starter...

[dlginla]

I have a Volvo Penta V6-225-A in a Regal 2013 boat. One day fine, next day turn key, everything powers up as normal, no response from starter. So checked starter, good, checked power from key ignition, good. Checked starter relay switch, good. Checked power to relay when key is in start position (turned right), good.
So from the Ignition relay to the starter solenoid the connection is not there and no power is sent. So is there a fuse in between the two points, or something that could break the connection. Attached is the top view of the motor. I am looking for the next thing to check.
Any advice would be great.

Welcome
Don't have a diagram for your motor but in most cases there is a start assist relay which energizes the starter solenoid on the starter.

Key yell/Red to start assist relay
Larger Yell/Red from start assist to starter solenoid

This is a older 4.3 GXI but should be the same

Thanks for the reply, I have seen other diagrams, but you cannot locate an item on the engine by looking on the diagram. I was hoping someone would snip a pic of the engine and circle where I should be looking for a fuse or assist as you mention. Looking at the motor, from the relay the wires go into a bundle and at the starter the ignition wire comes out of a bundle. I cannot find where the wire would be losing the power.

So again looking at the diagram above, it shows what I thought , from the relay to starter there is no fuse or break, I will now have to take out and jump the relay and test the wire at the starter end.

Could swap the relay from the Trim to the start assist, in my drawing it shows same type, but check yours

Final: Found the problem, followed the above wire diagram, relay sends power through a big 40amp fuse (M2) before it circles back to the relay and goes to the starter solenoid. That fuse was blown, very hard to tell. Thanks again for the diagram it helped solve the problem.
