SS1 DIP Beam BIG improvement - Relay

Post by td99 » Sat Dec 12, 2009 9:21 pm

Since Mario's thread has been hijacked by "Flashers" I thought this worthwhile a new one.

Original situation
Battery 11.8V (engine not running, lights on)
Dip beam 9.4 V across bulb filament
main beam 10.8 V acoss bulb filament
Measured at rear of headlamp.

NOW
Just 0.3 V decrease in voltage across dip beam bulb!
Lots more light :D :D
The video shows the differrence

Today I had a good look at the situation and, with a minimal effort, increased the dip beam light ouput very considerably!
It will also prolong the life of the dip/main beam switch!

30 mins work, 1 relay, 4 spade terminals and 50 cm of wire. Functionality unchanged, Headlamps still fused.

My original idea was to run new +12V wire to headlamp area. But this is not necessary.
All you have to do is:
disconnect the dip beam supply (right hand wire in photo) from fuses A1 & A2 in the fusebox and use this to drive a new relay.
Add a new relay that supplies +12 V direct from battery to the existing fuse box connection in place of the wire previously disconnected. I soldered this to make sure of a good connection.

The contact in the fuse box can be removed by poking a small watchmakers screwdriver on the outsides of its contacts from above.
The photo shows both the original connection and the new.

Here you see the old wire extended with new section for connection to relay

Here's the relay mounted neatly beside a couple of others - I used the earth wire to one of these for this relay too.
Yes, I have the battery in the boot, so made a +12V connection in its place

Excellent explanation/ pics. I feel some tinkering coming on.

ps - will this affect my ability to use my flash to blind oncoming traffic :wink:

Mario,
Functionality of all switches should not be affected.
