Installed 2 new batteries and a Leece Nevill 230amp alternator and now the truck won’t start/crank/turn over. Any ideas?
stick that end on the positivebattery post or run a wire from the other end to the battery to see if it will crank
It’s sparked but that was it. I then changed the starter and got the same result, just sparks. Batteries are brand new and fully charged.Passenger side battery is the main for the starter
Driver side battery is the main for the electronics
yes, they both share some of the load, but if the RH battery is bad or it's connections -- the engine will not start
you said that you used the jumper wire and nothing happened??
no clicking? no sparks?
that wire is direct to the starter solenoid
so -- either bad battery, bad connections, bad starter
That wire runs directly to the starter solenoid -- the solenoid should at least click -- if you only get a spark suspect the solenoid is badIt’s sparked but that was it. I then changed the starter and got the same result, just sparks. Batteries are brand new and fully charged.
