W-T Mod Early 1998.5 Need Assistance


Recommended Posts

I’m finally getting around to replacing all the battery cables and doing the WT mod. I have a very early 1998.5 24V, and all of the other posts and pictures about the WT mod seem to be on later second gens.

I have pictures attached with markups. Can someone please confirm I’m on the right path.
Thank you!!!

I wouldn't do anything until more say what they have to say. I am not sure about any of what your doing because your factory set up is different than both my second gens of which I did the W-T wire harness mods myself.

 

Let me ask.. have you tested the level of AC ripple/ noise before starting this task? Your factory set up looks better than both my trucks (01 and 02) that had important connections made with some sort of glue instead of  actual solder.

 

What level of AC noise are you currently getting?

  1.  leave that ground attached to the head.  You may want to clean the connection there.
  2.  Reattach all the connections to the back of the alternator, one cable is for the ground and the other cable is the B+ charge which will be routed to the positive terminal on the right (passenger) side battery.  The other two wires are for voltage control from the PCM.  The blue wire is where you can install a (5-7.5 amp) fuse for PCM protection.
  3. It's not that much work to open that wire harness to expose everything.  If you disconnect the alternator charge wire at the PDC you will then have its full length to work with when routing it to the right-side battery via a fuse or circuit breaker. 
  4. When you open the wire harness up you will see where the ground wires are all joined this where you want to make your cut so that you have enough wire to work with and have a clean looking job.

Level of AC noise was about 0.045V to 0.048V

 

The same ground connections are glued together (see the 4th pic)

 

I am sorry your right. I need to stay out of these threads if I don't take time to look first. :nadkick:

The remainder of the charge wire is used for a ground to the left battery coming from the new bolt and new ring terminal at the back of the gear case.
