Gen I Volvo Schematics

Mark & Dale Bruss (Bruss) has downloadable Gen I Volvo PDF Wiring Schematics as well as a few of his personal wiring schematics on his web site from projects he's done on his 770.

After reviewing the schematics if your still having problems with wiring problem here's a cut and paste of a recent post by PSD_Tweaker (Rick) that might be of some help.

From PSD_Tweaker (Rick):
If your still confused with an electrical problem you can't figure out Volvo will fax you what you need, and give you some technical advice as well.  They cannot pin-point your problem any better than members of the forum can without being there to inspect the problem ourselves, but they are well versed in Volvo electrical gremlins.

Call: 1-800-52VOLVO - Then press one, then press one for "open new case file", then ask for technical assistance.  You'll get Mike, or Steve.  Ask for a wiring diagram that highlights your headlight switch, lighting circuits or whatever wiring related problem your experiencing.


Gen I Volvo Fuse Labels

These labels are often discarded when new drink holders are purchased or the top fuse panel access cover is replaced.  If you still have fuse block labels, please take photos and submit them.  Note, the fuse block labels are engine and transmission specific.  Most of the fuse locations are the same but be aware there are differences.


Gen II Volvo Schematics

Volvo has put many of their manuals online for download at Volvo eMedia Center.  Follow the links and select your trucks parameters and see what you can get.  It looks like in the area of schematics, Gen II Volvo are downloadable while Gen I Volvo schematics are for sale only.  But them you can go to the link above for Gen I Volvo schematics.  This was from a tip by N20N1 (Ed).

We have downloaded several schematic pdfs from the Volvo eMedia site for your convenience.
