Early CVH?
Is the starter on the nearside, together with relay/solenoid on the bulkhead?
If so, is there a reasonably thick brown wire leading from it, through the bulkhead and back out to the fusebox just ahead of the toolbox on the offside? If so, is there any fuse / breaker before that wire goes in behind the bulkhead?
If not, I recommend a fuse is added. I can post a photo from my X-Flow where I added one (there was a good reason for its addition after I had to do a partial rewire!).
