L3314HD Laplander Alternator Conversion

    Aerodynamic drag coefficient - Cx


A few years ago, Chris A. contacted me about converting the Charging System of his unique Volvo Laplander, civilian version of a Swedish military utility vehicle, to the proven SW-EM Delco installation.  Since this vehicle is also powered by a B18, also with a Bosch Generator based charging system, it seemed like a good option...

After carefully considering the details of his somewhat special installation, and doing a bit of additional electrical engineering Kung-Fu, I sent him a (modified) kit, which he installed. 

Some of his initial comments: 

"Tightened everything up - she started right up and the [AMP] light went out... All good.

Wipers move quicker.  Lights are brighter.  Stereo can get bigger!"

Chris' Laplander...ready to take on almost any road or non-road...in any weather conditions!


Wiring Diagram of the L3314HD is quite different from it's civilian contemporaries, but similar to those we are used to seeing...of note to the author:  140 style, 12 station Fuseblock, no armored Ignition System, and dual, individually switched, Wiper Motors:

This vehicle is truly unique, so I thought I would follow up with him after a while of operating with the new Charging System, and get his long-term impressions, and maybe a few more pictures of the Laplander in action...

...so after two years: 

"Itís all working perfectly still...  Your upgrade is a no-brainer!"  

[That's what I like to hear!]
