Title: Electrical accessories & charging system capac
Post by Redfire_05GT on 04/16/07 at 13:29:04

How many watts of electrical accessories can be added to an '05 S40 before overloading the charging system?

Looking to add: driving lights - 70 watts; Hot grips - 35 watts; heated vest - 35 watt, or jacket liner - 47 watt.

Last time I calculated it out, I think I came up with 80 or 90 watts for accessories.

PIE P= I x E
P=power / watts
I= current / amps
E= electromotive force / volts

14 amphour battery x 12 volts = 168 watts per one hour untill battery is dead when engine not running( not charging)

2 ea. 20 amp fuses(fuses are sized to wire gauge so fuse blows b4 wire burns/fires/smokes)
SO ..... 20a x 12 volts =440 watts
the difference is a safety factor to allow for inrush current
usually 125% of load....my way around these low capacities is replacing lighting loads (bulbs)with leds..
some here have had good results with 2 x 70 watt light bars but me thinks no other extra loads...
was a post last year about the alt/rectifer output...some serious capacitors and proper wire sizing/fusing???
