Title: 1.3s Sport Lighting Post by: kevbo on 30 October, 2016, 05:14:13 PM Hi all, I've been trying to improve the dipped beam light output on my S2 Sport. The main beam is very good giving a nice white light, the dipped beam though is a bit yellow and weak.
I've had a go at cleaning up various earths local to the lamps but noticed that the volts at the lamp are about 11v with battery at 12.8v (idle). At the fusebox, volts at dipped beam fuses are around 11.5v. So, is my problem the solenoid output?should the volts at the fuse be close to 12.8v? I have halogen lamps fitted. I've also got a dim generator light on all the time the car is running but the volts across the battery approach 14v when the engine revs above idle. Also the main beam warning lamp is very dimly lit too. I guess this is poor earthing? Thanks Kevin Title: Re: 1.3s Sport Lighting Post by: nistri on 03 November, 2016, 02:17:28 PM Dim red light may simply suggest that the wire from the alternator back to the switch has high resistance (bad contact/wrong size etc).
More difficult is the issue of dim dipped beams. The Zagato has different electromagnetic relays from the coupe: maybe the wiring is simply incorrect. This needs careful checking bearing in mind that the circuit is always positively charged and that switching on the lights simply grounds the related circuit.

I have a glowing (dim) gen warning light on my S2 1600 sport but have yet to change the bulb. I routinely check the charging when the engine is running which is easier than distrubing the rats nets of wires behind the dash board.

ALLEZ LANCIA Lancia France Network - Information Bulletin Number 76 26th Jan 1970 Workshop note Subject: Flavia Berline 819 - fitted with alternator --------- You may notice under certain conditions, and especially whilst driving at night, a slight glowing of the alternator charge light. This slight glow is not, as one may think, a charging fault. In order to avoid this inconvenience, we advise you to replace the 3w dash warning bulb with a 4w bulb |
