Malcolm Clarke Posted July 26, 2011 Report Share Posted July 26, 2011 Am I missing something in the wiring diagram or were all TR6,s minus any fuses in the headlamp circuit ? Quote Link to post Share on other sites
PILKIE Posted July 26, 2011 Report Share Posted July 26, 2011 Aaccording to my wiring diagram the light fuse is the 2nd in from the left. Covers all low/high beam,side,instruments. Quote Link to post Share on other sites

Malcolm Clarke Posted July 26, 2011 Author Report Share Posted July 26, 2011 According to my diagram it looks as though the side,and instruments lights are fused by the second fuse down. But the headlights get their feed direct from the lighting switch or should I say via the ignition switch/ammeter and therefore battery/alternator. But no where does there appear to be a fuse. Surely a bit odd. Quote Link to post Share on other sites

PILKIE Posted July 26, 2011 Report Share Posted July 26, 2011 Turn your lights on and pull the fuses,see what happens! Quote Link to post Share on other sites
Malcolm Clarke Posted July 26, 2011 Author Report Share Posted July 26, 2011 Thats what started this off. Turn headlights on. Remove fuses. And headlights are still on regardless. Maybe that's how early TR6's were wired... But seems a bit odd. Quote Link to post Share on other sites

Maybe that's how early TR6's were wired... But seems a bit odd. Most British cars of this era (and earlier) did not have fused headlamps. The only fuses were: Auxilliary circuits which took a fused supply from the from the Ignition circuit - Purple wires to horn etc Instrument circuit which took a fused supply from the ignition circuit - Green wires to instrument regulator and turn signals etc Side lamp circuit which took a fused supply from the Lighting switch - Red wires to sidelights etc The fuses were there to protect the loom, not the lamps. Lamps are easy to replace, looms are not. I would not want a 'headlamp fuse' to leave me without headlamps on a windy road on a dark night. TT Quote Link to post Share on other sites
Peter Cobbold Posted July 26, 2011 Report Share Posted July 26, 2011 As far as I know its normal not to fuse headlamps, not just TRs. Perhaps its safer to be able to see the road as the cockpit fills with smoke than to be suddenly plunged into darkness Quote Link to post Share on other sites
Bald Rick Posted July 27, 2011 Report Share Posted July 27, 2011 I have a custom loom fitted in my car. It has most things fused (headlights, sidelights, wipers, heater, rad fan etc. including separate headlamp fuses for the left and right headlamps so that if one side goes down I am not plunged into darkness. It was expensive but having once had a loom fire in an AH Sprite I feel much safer with multiple fuses. Tony Quote Link to post Share on other sites
