My horse lorry will not start, I have fully charged both batteries but when you try to start it does not crank, all the lights on the dash are on and the air tanks buzzer sounds. I checked the headlights and they are bright as well, even used jumpleads to give a little help but same problem. both batteries were replaced in October. any ideas on what may be the problem
thanks

are you getting a feed to the solenoid on the starter when you turn the key ...sounds like the starter may need replacing

sound like the starter or a bad earth
