Vintage RV upgrades

Another basic info item, the converter/charger does not charge the engine starting battery on most rigs. This means that when you park the rig for a month in your driveway, the starting battery self-discharges. A brand new starting battery may start the engine after a month or more but an older one may not be able to turn the engine over. Batteries that are kept fully charged keep their capacity longer than ones that are run down, left discharged, and later recharged. Frequent checks of electrolyte levels, adding distilled water as needed to cover the plates and timely recharging of batteries is a necessity with RV's. You can use a 12 volt "smart" trickle charger to keep your starting battery up if you have 110vac available. I have an add-on Trik-L-Start device installed which keeps my starting battery up while parked for months. It is connected to the house batteries and shares charging current with them . Make sure that battery connections are kept clean of corrosion and are making good contact.
