Iv moved my battery into the boot so need some cable! What cable do i need " what guage" to run from the battery + to the starter and then onto the alternator ?
A good battery centre will sort you out and cut one up to the correct length and if needed put the right connectors on it. Search on eBay. A local one did one for my alternator to batt wire. £10 IIRC
Live long and prosper!!
170 amp cable will be fine try vehicle wiring products or AES both do it in metre lengths or rolls dont for get to use the same size for the earth from battery to body and body to engine.
