Final Note
The DC motors used on 12V DC burners can draw as
much as 20 amps! For the burner to run properly, the
battery and engine charging system must be kept in
good condition, and the engine must run fast enough to
adequately charge the battery. Do not throttle down the
engines for any length of time.
