headlites & horn
 

I have dim headlites, high beams seem ok and horn is weak,sounds like bad ground not sure if there on the same ground cricut also were to find that ground connection.

Trace out the battery wires and check the ends. Check battery ends for clean and tight. Disconnect 1 of the batteries, does lights and horn get better? Reconnect battery and do same test to other battery. You very well might have 1 bad battery dragging you down. Or go to Auto Parts and they should be able to check your batteries with a load tester. Or buy a cheap hydrometer and check for a dead cell yourself. Cold weather plays a large part of battery failure.
