Hi — what's up?

Pick how you want to diagnose the fault.

Quick Fault
Tap each step as you check it off.
1
Is the battery isolator switch ON? (Big red knob, usually near the batteries.)
2
Check the main fuse / circuit breaker for the affected circuit — is any fuse blown or breaker tripped?
3
Look at battery voltage — should be 12.6V+ at rest, 13.8–14.4V running. Use a multimeter if you have one.
4
Check obvious connections — any green/white corrosion at terminals? Anything loose, wet, or smelling burnt?
Still stuck? Tap "Describe My Fault" and tell ElecBot what you've found — it'll take you the next step.
