paul connor Posted January 29, 2009 Posted January 29, 2009 Right,Here is an odd one.. I have re-installed the stowage box in the rear for the radio charging system. I have also replaced the headlight units and opted for Xenon bulbs. Now somewhere along the lines something has gone wrong and I cant figure it out. Upon driving this evening in the dark, the charging light is glowing very slightly. If I put on full beam and the penthouse lights it gets slightly brighter. The alternator is charging. I have checked all visable connectors which all seem tight. the batteries seem to be getting 12.5-13v reading indicating a charge coming in.. But what might be causing this? Also! the headlight Blue light in the dial for indication of full beam now stays on very dim. Enough to notice.. Have I missed something? Quote
R Cubed Posted January 29, 2009 Posted January 29, 2009 If it is charging you should get about 13.8 volts at the battery can you check with multi meter ? Could be a bad earth, have you disturbed something or a bad connection in one of the headlamps and causing a back feed through the main beam ind light !!!!!!!!!! Only guessing though Quote

Tony B Posted January 29, 2009 Posted January 29, 2009 I had something similar on the 101 (The electrics designed by a plumber) in my case the charge light. There is probaly a shorting to earth somewhere, possible two wires touching. All I can say is you'll have a lot of fun finding it. :shake: Quote
sirhc Posted January 29, 2009 Posted January 29, 2009 Paul, I thought Xenon bulbs were like flourescent tubes and pulsed so many times a second, therefore they require a seperate power supply. Are you sure they are Xenon bulbs? Chris Quote
R Cubed Posted January 29, 2009 Posted January 29, 2009 Opps left that bit out check the earthing in the head lamps first as this is what you have disturbed !! then go from there. Quote

Lord Burley Posted January 30, 2009 Posted January 30, 2009 Paul, I thought Xenon bulbs were like flourescent tubes and pulsed so many times a second, therefore they require a seperate power supply. Are you sure they are Xenon bulbs? Chris You can get Xenon bulbs,that are just filled with a xenon gas.These are the cheap option,and should not be confused with H.I.D units that require a seperate ballast. This is what proper H.I.D lamps look like as fitted to my 90..................... Normal xenon gas filled bulbs dont produce this intensity of light. And by the way i think the dimly glowing light is the diode pack on the back of the alternator on its way out. Quote

I don't think anyone knows how Land Rover wiring works not even Land Rover. I drove one once, the engine would not stop while you had your foot on the brake pedal. Quote
rambo1969 Posted January 31, 2009 Posted January 31, 2009 That looks like a certain place near me where, erm, ladies of the night hang out! Quote
Lord Burley Posted January 31, 2009 Posted January 31, 2009 Nope!.This is south of the river.Brixton to be precise.Heart of gangster land. Quote
paul connor Posted February 4, 2009 Author Posted February 4, 2009 Does anyone have a wiring diagram? I need to confirm my set up has not been tampered with as much as i think it has!! many thanks Quote

fv1609 Posted February 4, 2009 Posted February 4, 2009 Does anyone have a wiring diagram? I need to confirm my set up has not been tampered with as much as i think it has!! many thanks Don't always believe the circuit diagram. One of the diagrams has the radio battery link between the two 12-v batteries going to earth! Which installation do you have Paul, the Gen Panel No.4 with single ammeter or Gen Panel No.3 with 2 ammeters? Quote
paul connor Posted February 5, 2009 Author Posted February 5, 2009 Right.. been playing all day with the FFR Seems from the ammeter there should be 2x live cables for charging.. one to the rear stowage other to the front batteries.. One had been cut half way and was not connected! so I was not charging. and my other live was sitting on the stowage box! which does not help! hence my alternator light coming on very dim! as the front batteries become discharged SO now I have 2 sets off batteries charging! only odd thing is the front set at 25.2V aned the rear seem to be 26.8 I assume this will be so until both sets are charged? Clive, I have a single Ammeter Quote
fv1609 Posted February 5, 2009 Posted February 5, 2009 (edited) Single ammeter implies the transistorised regulator in Gen Panel No.9 Mk 4. Hope this helps, although the feed to the vehicle batteries (31) is wrong! It should not go to the battery link! It should of course go to +ve terminal of upper battery of the pair comprising 31. 31 vehicle batteries 34 radio batteries 49 shunt 46 ammeter 44 light bulb for ammeter 45 push switch for light 48 fuse (radio batteries) 47 +ve terminal post (for vehicle batteries & light supply) 67 Gen Panel 72 Generator 73 filter unit, which I have never seen fitted, is to protect sensitive radio equipment from voltage spikes Note that the +ve supply for radio batteries & vehicle batteries are independent. They are only connected in parallel inside the Gen panel when voltage from generator is adequate & then are also connected to the main output from the generator.
