Onan Generator Cranking Amps
What is the expected cranking amp draw for a Onan 10K generator? Mine is cranking slow due to excessive voltage drop on the + wire and I want to estimate what the voltage drop should be for the wi...

Gjac,
Great advice and in fact I carry heavy duty jumper cables in the car.
Using the battery boost/emergency start switch improves starting and it's even better with the 200A engine alternator running. and I'm aware that can suggest battery issues. However that does not explain the 2.1V drop on the positive wire.
I will determine the wire gauge used and it appears to be 2 or 4 gauge. However it might go the the front run panel FRP and connect to a larger wire. Once I have this information and estimated lengths with the above 197/207A draw a wire calculator will provide the expected drop - good to know. Corrosion and lugs will be checked. Then I'll know how best to resolve the issue.
We're headed home and other priorities will delay further investigation.
