Can I check how folks are routing the cable down to the solenoid?

I've followed the routing of the old cable, across the clips by the twisty grease doodah, around the edge of the edge bay to the handbrake area and then down close to the doghouse spring clip immediately above the solenoid.

With a bit of wobbling the cable has moved close to the exhaust manifold (actually to the point of touching an old earth cable that was about to get very hot....) hence this is clearly not the best routing.

There's a smaller diameter cable loom running through some metal clips in the area that look battery cable sized - are these supposed to be for the battery cable?

The battery cables run right along the frame, inside the frame

Hi Lauren,

As Stew says, the standard battery cable route to the solenoid is along the inside of the RH chassis rail, as in the pic below. However I notice in your first post you have an F22. I'm not familiar with the F22, but from your description it sounds like it has a battery box inside the cab, like the FGT. If that's the case, you may get some answers if you post this as a FGT question.

Cheers,
Tony

It does indeed have the battery box inside the cab, on the opposite side of the cab to the solenoid, hence routing the cable across the back of the engine bay and down.

It may be that this is just one of the oddities with my vehicle and there's no good route given the full cab. I hadn't considered that most CMPs have the battery box out by the step.

I have been starting my 15 FCMP A for 20 years plus. It is 6 V. But I have a 12V in the toolbox and a 12 V selenoid attached to the frame just behind the 6v. This 12 V only needs to be charged 2- 3 times a year. If I am out for an extended time an the 12 V runs down, the 6V with a fresh recently run engine will start on the first tap. A dry carb rasies hell with a current 6 V battery

Hi All

Engine starting on 6 or 12 volt, either or approach. Being a bit of a purest I have retained the 6 volt electrical system on all three of my CMPs. Being blessed with easy starting Chevy engines the 6 volt has not let me down very often. Generally only when they have sat for a long time or in very cold weather or when something else was wrong that more volts might or might not have helped.

But like Bob Estabrooks one of my trucks is set up to start on either 6 volt or 12 volt. When I installed the 261 engine which was designed for 12 volt I did have some concern that the 6 volt would not be able to do the job. But as the C60S has a 12 battery for radios, lights in the box and water system, I installed a selector switch which allows me to connect just the starter to 6 or 12 volt battery. So if the engine doesn't catch on the 6 volt a flip of the switch and the 12 volt spins the engine over.

Only draw back is that the charging system will recharge the 6 volt battery.
