48V Precedent, 18 month old Trojan batteries, stored in Golf Course "cart barn.
Not sure if weather has anything to do with it (cold and wet at times).
When initially trying to get it to move at all, I have to pump the accelerator, turn key on and off several times, and even switch forward and reverse many, many times before the cart will move. After that, if I stop for more than about a minute have to pump the accelerator several times (or more) to get it to go again. Gets "better" throught the round but this is beyond ridiculous at this point. Reading through posts on this, I get the impression it might be the solenoid. Opinions/guidance please. Would like to have some ideas of what the problem might be before I take it to the local repairman (who tends to overcharge for everything.)

Thanks in advance.
