Junk do not use on a boat, only on a junk? Wink
To get the correct crimp pressure, it is always a good idea to ensure that you are using the correct crimp for the wire size. If the wire is loose when fully crimped, one or the other needs considering.

Of course it'll work. (It hasn't caught fire yet).

i bought a neilson ratchet crimper for 'standard' red/yellow/blue connectors (after struggling for years with hand pressure only ones), however i only get a good crimp on the yellow size, despite going to full travel on all three.

On the ones I have there is an adjustment that determines the pressure and release point on the ratchet crimp tool.(i think there is a release screw and an adjustable cam to set up)
Just check yours doesn't just need adjustment first.


I've never been able to adjust my crimps so they work consistently with all sizes of connector, or even with different batches of the same size connector from the same manufacturer - basically i always do them as tight as possible and give a good yank afterwards to feel if there's any movement.

I have used soldered joins onto the back of a car alternator for many years without issue - although I probably crimped then soldered even back then.

I use a draper and I've never had a problem with it. It does double crimps. I'm hesitant to recommend them though because some of their other tools are gawd awful. I had an angle grinder from them set fire while running in my hands going through 4mm aluminium sheet and a grease dispenser that is now made of rust because the paint wasn't grease resistant.  Roll Eyes

For those with troubles. Excuse my laziness this is a ferrule crimper not a crimp crimper but the torque adjustment screw is the same.

ha ha brilliant, it hasn't been running for about 5 months, so i'm looking forward to having it back
Next little upgrade is replacing the head lights with led floods i bought as well as installing some at the back for work lights.

And i'm about to start a project to complete the missing loader parts so i can use it as an actual loader
