Blew the low beam headlight fuse checking for voltage. Have not been able to find fuse location. Anyone know where to look on a 2010 36QSP bus ?

Thanks a bunch.

You might not have one. I had both my low beams go out and spent some time hunting too. Finally called Tiffin and they said no fuse on the 2013 Bus, check the bulbs. Sure enough, both blown. According to the Tiffin tech my lights are run by 2 computers in the left front basement compartment and are subject to spikes that will blow both bulbs. Two new H-1's and I was back in business. Lot more pricey than a fuse though. My first time for this issue in 95,000 miles so I can't grumble too loud.

Pigman,
Lost DS lamp while back. Then PS side as well. Never drive at night anymore so just now getting around to fixing. Had power at H1 harness plugs. But then wanted to check H1 pigtail plug at lamp. To confirm blown bulbs for sure. H1 only has one blade connector ?? Got spark at tester probe. Now no power at either side.
Tiffin told you they were on the VMM units ?
By the way how are the H1 bulbs removed/replaced. I unhooked the wire clip, but bulb not moving. Pull harder...twist ???
Thanks

Yeah, they're on the VMM's. Your big tag should tell you which lights on the boxes should be lit when on high and low beams. On mine the harness that plugs into the bulbs is a 3 way plug, 2 vertical and one horizontal. I pulled the plug, then pulled the large rubber splash guard off. Unsnap the wire clip and swing it back out of the way and the bulb and mount fitting should pull straight out. Might have to apply side to side or up and down wiggle to it but it comes straight out. No twisting. My local Walmart was out of H-1's so I had to get them at a local auto supply. About $40 if I remember correctly.
