Hi skollob,Thanks very much one and all. I really am an electric simpleton, wouldn't try to add relays to be honest... sad I know and I am embarrassed by it.. most I ever managed was rewire the arse end of my Landy. I'll look at the other options mentioned. But prob stick to halogen for simplicity and cheapness. Do know a local sparky who would help me out needs be.
When Blue was working 10 miles away through last winter, going to work in the dark and coming home in the dark. Lights on (halogens) heater full chat and wipers going, In her Moggy with original dynamo and wiring, Never had a problem with the battery, and its only a little £30 battery. It now does little bits of running here and there, still no probs. My Cortina used daily, some long some short journys. Its got a 12 cd changer thats allways on, no problems either. Just saying that there is no need to fit an alternator, if you are killing the battery with normal use ( even with some extra lecy stuff) its cus the dynamo or reg box is faulyty, And normally easily fixed.Yep easy to fit a relay,well easier than rewiring lol
Also if your running a dynamo you might want to fit an alternator,otherwise your battery won't last long!!
