Chris, I have attached a technical email I did some time ago which details how to install a high beam relay on a 1600. It just may help you unravel your headlight wiring. It may be easier to pull the altered wiring out and do it again properly. As the 1600 lighting circuits are "hot" wired the high beam circuit is earthed at the steering column harness and the low beam is earthed at the light switch. Also check that the top 3 fuses on the right hand side of the fuse box have 12v on both sides as the copper holders can get tarnished which gives high resistance and this will also give the symptoms that you have described, particularly the earth leakage through the inners when your on low beam. regards Terry -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of uniken Sent: Friday, 2 February 2001 12:27 To: [EMAIL PROTECTED] Subject: Headlight Woes Hi everyone, I'm having a problem with the headlights on my 1600. The left one is very dim, and the right one a bit dim too. The high beams (inners) glow slightly when low beam is selected. The voltage at the lights is 12 when they are off, so I presume the switch earths one of the wires. When the light is on the voltage drops to only 8. I think I have a bad earth somewhere or maybe a bad relay or switch. Someone has added several relays (for two extra sets of lights) and fiddled with all the wiring. Where is the earth connection for the headlight switch located exactly? I connected a new earth wire from the battery to chassis, but it did not improve the situation. All the other electrics function properly. Any help much appreciated!

List, This is a repost of the high beam wiring info that a number of you have requested. regards terry ========= I will supply easy to DIY details for wiring a high beam headlight relay in a 510. In this example I will use the relatively inexpensive Bosch 30A mini relay, although for serious lighting, say above 300 watts use a relay such as the New Era NLR-132 which will supply 2 fused 30 amp circuits and works great for 4 super Oscars on the rally car, a bit much for a road car though. The Bosch 30A relay is found in most auto parts shops and has numbered pins to make it easy to wire and is rated to take 360 watts in theory, but I usually limit these to 260 watts continuous for road use. Preparation You only need to cut two wires on the 510 or optionally use 2 male spade connectors to connect the high beam circuit to the relay. The inner headlight plugs have 2 wires that connect from the plugs on the outer lights. On the drivers side the wires are "red" and "red/white trace" and on passenger side they are "red/blue trace" and "red/white trace." You will also need some quality female spade connectors and wire - some 30 amp for power and 15 amp for the lights, a 30 amp metal or Bakelite in line fuse, don't use plastic holders as they melt very quickly the first time you go for a drive in the country. Disconnect the battery or remove the headlight fuses for both sides. Remove the existing plugs from both inner headlights. Pick a side (I prefer drivers side) and cut both wires as close to the inner headlight plug and bin the plug. Tape the other side plug out of the way as it also is no longer used. I prefer to solder connections rather than crimping but that's personal choice stuff. You will need to solder the connections for the in line fuse. On some 510's the inner light wires that you cut are a little short, so you may need two insulated wire connectors to lengthen these wires in order to reach the relay mounting point. For mounting the relay on the driver's side (preferred) Pin 30: +12v in line fuse recommended from starter, battery or alternator. Pin 85: Connect the "red" wire. Pin 86: Connect the "red/white trace" wire. For mounting the relay on the passenger side (note the battery power feed to the 30 pin will be much longer). Pin 85: Connect "red/blue trace" wire Everything else is the same as drivers side. There are 2 x Pin 87 Pin 87(1): Connect to +ve side of drivers side inner headlight Pin 87(2): Connect to +ve side of passenger side inner headlight. Route underneath the cross support for neatness. To eliminate the chance of shorting out, I recommend for the +ve wire that goes across to the passenger side you used a shielded wire. Lately this stuff is only available for 2 or more core, but that's ok. Mount the relay on the inner guard, I put them about 3" back from where the bonnet cable goes through, there is a ready made spot that the auto has the inhibitor relay mounted. Earths: Connect -ve side of both headlights to a good earth on the body. Reconnect battery and fuses and enjoy your new lights. With a relay installed for the inner lights, the standard outer relay will supply 60/100w both sides without problems. This job really is easy, take your time, plan the task well and you will have a headlight relay up and running in your 510 in no time at all. ========== _________________________________________________________ Get Your free Ozdat Email Account ---> http://www.ozdat.com --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.datascribe.com.au/ozdatonline/index.htm http://www.datascribe.com.au/ozdatonline/listindex.html http://www.mail-archive.com/[email protected]/ ---------------------------------------------------------------------
