Re: Alternator Upgrade After Installing Heavy Electrical Accessories?

Today's Update,

Just completed the work in my car, it working fine, with all the load I am able to get 13.60 in idle rpm and if I just increase\accelerate a bit it raises to 14.20. I think its more than sufficient.[;)]

Tested with full load.[evil]
Headlamps 120\100 watts,fog lamps 55 watts,blower, front and rear wiper, engine\radiator fan, brake light.

The alignment is more perfect than the first car.
Here are some pic's taken at the time of installing.
Sorry for the picture quality .
I will upload the pictures of the mount and other wiring later.

I guess, its charging over the limit.. is it ok if it charges in this manner ?
The max it should produce 14.40 volts .

Re: Alternator Upgrade After Installing Heavy Electrical Accessories?

Oh, But I found out one thing, The above values (16.7 to 18 volts) are found only when
the car is started for the first time in the morning (cold start).. after few minutes if I turn off and switch on the engine, its back to normal.. that's 13.5 to 14.30 . So whats the magic behind this ? Pls help me sort this.

Re: Alternator Upgrade After Installing Heavy Electrical Accessories?

I think this thing happening during cold start only is due to the fact that the RPM is on the higher side when you cold start the vehicle. If you try to listen to engine RPM (you can see as well if you have RPM meter attached), you will notice the same for few seconds/minutes and this recedes to normal after that. I think there is no harm in this but as illango sadi "Till then enjoy .." [cheers]

@Varun
Unlike all your DIY projects, this one lacks the budget factor.
Please post the cost involved in this project if you remember.
Sorry if I have missed to watch in this thread somewhere :sorry:

You should be able to find a used alternator for 3.5-4k get it serviced and follow the instructions about the mounts that Varun has posted.

So the overall cost would be close to 5k.A new 70amp alternator itself costs close to if not above 10k.
