No power/start

[Strategic Tactical]

Been a while since I've posted but the truck was running great until a couple weeks ago. I went out to start it, flipped the accessory switch and no buzzing noise indicating low air pressure and no reading on the battery guage on the dash. Batteries are charged and connections feel tight. With it being a 24 volt system, I don't have any "testers" to check. Where should I begging and where can I get a good tester that will hold up to the 24 volt system?

Start with a cheap Digital Multi Meter (DMM) you can get at Harbor Freight for about $10.

They also carry a test light kit that includes 18/24V Light along with 2 others.

Pick up a hydrometer at your local auto parts house. Used for checking specific gravity in electrolyte and coolant. Once you get the battery situation solved, purchase a 24 volt all-in-one charger, maintainer, desulfator.

Just because the connections feel tight doesn't mean that the connections are good. Disconnect the battery cables and clean all of the posts and connectors. Make sure the cells are topped off to the correct level with de-ionized water. If you don't have a 24 V charger, you can charge each 12 V battery separately with a 12 V charger. If you still have a problem, check the ground connections.

It doesn't take much to stop electrcity. Yup check\clean connections. I've also seen corrosion start inside a power cable. It looks fine on the outside but is full of green dust when cut open. It could also be a bad power switch.

Agreed, And inside the Battery terminals. Buy a hydrometer, that is proof positive for checking battery condition.

All very good suggestions.

Master switch, or a rodent ate a wire somewhere.
