    I have a 6 volt forklift that will not start with out 5-10 minutes on the battery charger.. Runs fine once started, new battery, alternator is OK, and I even disconnect the positive terminal and still not enough juice to crank it.....

    Help....

    Thanks

    I don't know these machines but, if I could offer some advise. Just make sure the starter motor is ok. I have, in the past, seen machines acting like this and it's turned out to be a 'lazy' starter. (come to think of it, I know some blokes like that:rolleyes:)

    Good luck Phil

    Mmmm, tough one that. It's worth checking the earth lead from the battery to the chassis and from the chassis to the engine. Could be breaking down. Good luck Phil :)

    I have been told the 6 volt systems can just be like this.......I would like to sell the unit but this little issue seems to be scaring people off.......otherwise the unit operates great...

    Could also be a dirty/corroded switch. Can you disassemble and clean the contacts? Take a volt meter and see where the voltage is dropping at. Test at the battery and compare to each point down the line toward the starter (solenoid, switch, safety switches, etc). Are you getting close to battery voltage at the starter? Is this thing British, you may need to refill the lucas smoke bottle (just razzin Phil a bit).

    Just a thought, check your battery cables. 6 volt systems draw twice the current as 12 volt so you want real heavy battery cables like 2/0 ga. The normal cables used for 12 volt systems are not heavy enough and will often cause the problems your describing.
