Is there a way to check the headlights to see if the high beam is burnt out? Hate to replace the lights and maybe still have the same problem.

jump power and ground directly to the headlamp to see if it's burnt out.... | | | | | Joined: Jul 2005 Posts: 2,031 Shop Shark | | Shop Shark Joined: Jul 2005 Posts: 2,031 | don't forget to check for power and ground at the headlamp,
if there was a bad ground he wouldn't have low beams !!
maybe as mentioned an open circuit for high beams probably close to the foot switch.

unless he has what some of us have
a separate circuit for each. i run two relays ... one for each Lo/Hi beam
it's easy to trouble shoot.
