    Hello everybody, so I started a new thread for this as I am hoping that it will be a vendor recommendation thread and I wanted it to be easily searchable.

    I installed my b&c starter and the wire is about 6” too short. Does anyone know where to order a prefabricated piece of large diameter wire?

    I don’t need it quick, I still have to cut the old one out and take measurements.

    I ordered my wire and terminals from ACS. They also had a crimper for about $14 part number 12-03719. I’m not sure if they sell assemblies though.

    Having your own crimper would allow you to crimp your terminal in the correct clock position on the wire.

    They are easy to fabricate if you have a crimp tool. If not, I believe you can buy a short four gauge extension premade by skytec. I think spruce sells it, p/n: BCE-6.

    In fact you don't even need a crimper for these large diameter wires. It is easy to crimp them in a vice. Use a suitable piece of steel to make the pressing

    Get the large, long, cable from B&C. They will fabricate whatever you need.

    The starter needs at least 10 guage wire. As previous posters have explained, just use a smooth jaw vice for the crimp. I soldered also.

    Every B&C starter installation requires rework of the wire as the B&C is so much shorter than the boat-anchor Presolite unit. And copper is what works best and is what is commonly used. Piper tried aluminum in their airplanes which created an aftermarket for copper replacements.

    You will also want a couple of the rubber hoods that Aircraft Spruce sells to cover the terminal ends once the wire is in place.

    The pictured tool is woefully inadequate for the job. Probably break.

    Best of luck,

    Wes

    A crimp with a large side cutter and then solder will make a joint that will last the life of the wire. But don't solder small wires, the solder will wick and create a stress point out beyond the connection and with vibration the wire may/will fail at that point.

    Use a cable swedger and the sell a tool that you whack with a hammer for big gauge.

    Are cable extensions kosher?

    I'm not an aviation A&P so can't offer much but an extension with good crimps and solder works fine. But at added weight, complexity, and additional failure points. Another words I wouldn't !

    I agree Larry
    B&C gave me a recommendation so I just need to get some detailed measurements and they will make me one

    Thank you everybody for your help. Still burning the midnight oil doing my second pass through the power plant questions and hope to have that test done soon

    While the beauty of an experimental is the ability to do kind of what ever you want...Steinair can build you a cable to your exact dimensions. They use aircraft quality connectors and wire.

    West Marine has the crimping tool on a bench in their store, at least in my town. I know the connectors would be large enough. Welding leads are used for battery wires. If the connectors in the store are not large enough or of the quality you want take your own. I know here I would not have to buy anything, of course that is the reason for the free use of the equipment. I would be happy with what they offer.

    will
