289D Starter Issues

[FLYWHEEL PRIME]

Key in, machine powers on, fuel pump working as it should. No errors or faults on display, no security system.

When I hold key for ignition, you can see the voltage dropping from 12.8 to 11.0, it is trying to push juice somewhere.

Can anybody help me with the start circuit locations? Is there a single relay and fuse somewhere? Assuming engine bay?

If you would like an electrical schematic then you're going to have to supply a Serial Number.
There are a dozen different S/N prefixes to choose from.
