Hi I would like to make a suggestion!
Bought a motor home some years back and discovered a lot of changes were made electrically, driving at night we had a light show under the dash lots of wires we’re arching.
I spent days trying to get it straightened out.
I would like to suggest that when people make changes to electrical they note it either in the manual or a note in the area of the fuse box effected buy the change.
I have worked on aircraft that had been modified or changed and nothing to indicate what why or where.
The next owner or years down the road when we no longer remember where we left the wife in the mall.
This info can be invaluable. Even to a tech you pay to work on your prized possession.
But do we really care
