I just bought a 1992 WhiteGMC WIA with a TD123EA engine and 8 speed manual Volvo transmission. It runs and drives great, but it has some electrical gremlins I need to root out with the instrument cluster, lights, cruise, etc.. I've searched over the web for reference manuals and have only been able to come up with a TD122 workshop manual in spanish. Is there a place where manuals can be had? Thanks.
Looking down at floor behind pedals you will find the ground wires bolted to fire wall under the trim panel, take ground wires off the bolt and clean them,
For anyone else looking for these manuals, I didn't have any luck finding manuals on ebay. But I did see that this truck is similar to the Volvo NL12, so I looked for manuals for that and discovered the digital manuals are incorporated into a software called Volvo Impact which can be found on ebay and online. For an old truck like this, the version is important as they purge older models with each update and only older versions contain trucks exported to North America. Look for Impact 2009 or older.
