1991 e250 wiring diagram??
 

Anyone out there have a wiring diagram for this era e-series?? I'm having regulator problems!!
Thanks

Hi Tony,
What kind of "Regulator" problem are you having, may be able to help ?

Alternator is new, battery is good, but not charging. Wiring btwn alt. and reg. has obviously been messed with, so I need to know the correct wiring up to that point at least. Help?? Thanks!!

Does your van have an ammeter or just an idiot lite for the charging system.
The hot lead on the alt goes to the "A" terminal on the regulator plug.
The "F" terminal on the alt goes to the F terminal on the regulator plug.
If the vehicle has an ammeter, then the wire from the ign switch goes to the "S" terminal of the regulator plug.
The "I" terminal of the regulator plug is not used with an ammeter system.
If this info is not sufficient you need to provide more info as to just what you have and what the charging system is or is not doing.
