Found this thread after several days of scratching my head why my brand new 95A alternator not charging... The PO removed the charge indicator bulb!!!
Put the bulb back in, alternator now charging nicely at around 14.3V, except when I turned the key completely to the left to remove it, the Battery charging bulb comes on... WTH? If I just turn the key slightly to the right (and nothing else energized), the bulb would go off but then I can't remove the key from the ignition.
Any help where to begin would be greatly appreciated!
Charging system mystery.

Re: Charging system mystery.
Is there a chance some one installed a Lada ignition switch in the car in place of the original Sepia? If so the Lada ignition switch has a pair of contacts that are mating when the key is removed.
Sipea switches have Sipea engraved in the shinny metal face of the ignition switch. Lada ignition switches have Roman numeral type symbols stamped in the shiny face at each key position.

Re: Charging system mystery.
Great advice!
Googled the wiring diagram and rewired it - now it works as it should! The PO had the blue wire on the INT terminal instead of on the #15 terminal with the pink wire.
Thank you for pointing out that I may have the Lada switch, that was the ticket for troubleshooting in the right direction.

Yep, no problem. Glad it worked out
I would add a relay when using the Lada switch though. They are cheap and the contacts are not exactly amazing.

Re: Charging system mystery.
Add the relays regardless of which ignition switch is in the car since the lack of relays for the starter, headlights, etc is the most common cause of the OEM switch failing.SteinOnkel wrote:Yep, no problem. Glad it worked out
