Increase voltage current supply 200 1989

89 b230f 240 sedan auto.

The car is in great shape. I recently added a pusher fan in front of the condenser for better condenser cooling (wow what a difference to the A/C performance). Wired up with a relay supplied by the compressor clutch trigger.

With that I find the current draw sometimes feels like it might be too much, when it triggers on, it drains the idle for a second or so. I will look into adding a delay to seperate the fan trigger from the compressor clutch, which will help, but my question is as follows:

Is there some mod I can do to increase the current/voltage supply of the alternator? Are there other model volvos that might have a larger alt or voltage regulator improvement? The voltage regulator is the original one with new brushes I replaced around a year ago. I believe it performs to spec, as I recall the voltage might have been 14.x while at idle. Never gave me issues.

Also I might convert the rad fan to electric and that will add even more electrical drain.

The battery is somewhat old 3 years 100K km now, but I think that really is only for cranking power...

Thanks in advance,
