Fuse #5 / 2 amp fuse?


Recommended Posts

Hello Everyone,

I blew fuse #5 / 2 amp  today during the installation of a USB/voltmeter. Installed the USB > turn the key on > USB powers > turn key off > proceed to install anti-bobble bars > turn key on and double check USB power before installing panels and no power to USB >  checked power to 2 pin connector with circuit probe and light does not illuminate > which led to finding fuse #5 blown. 


My question. Is fuse #5 common to blowing? My hopes are to charge a cell phone and maybe charge ear buds from these two USB ports. Can the 2 amp fuse handle this? 

Found it very odd for it to blow not charging any devices. 


@Canuck8 Hopefully you find the answers helpful.


Thank you everyone in advance for your answers,

@Leoh A couple of things to clarify if you would:


1. Were you working with the parking or turn signal lighting?  If you had the key on ( past Lock) in the P ( parking position) that's what energizes the #5 fuse. You won't notice anything different unless you activated the turn signals or hazard lights.  That's what the #5 fuse protects. 


2.  Where were you installing the USB/Voltmeter?  A lot of owners replace the cig lighter accessory charging port on the left side of the dash ( Auxiliary DC jack #1 on the wiring schematic).   That charging port is protected by fuse # 7. Have you checked that fuse also?


To answer your question,  yes, you can charge anything that draws a maximum of 2A from the Cig lighter ( Auxiliary DC jack). 


This link ( found in Tech Tips > Service Manual pinned topic) will help you trace down those fuses. The last 5 pages of this will be where you want to look.

@AZJW Thanks for the info. I believe at one time the key was in the ignition but not turned. 

As of today I'm good to go. I replaced fuse #5 > decided to connect the USB (right side install) to the 3-pin connector. I will connect a Garmin Zumo XT to the 2-pin connector in the near future.
