Why do you think I keep posting?

I found the problem. 15 amp fuse feeding headlights & indicators ( possibly others as well). 2 x 60w headlight bulbs=10 amps. I haven't had chance to check the spots, but assume the same wattage & we have 20 amps of lamp load alone

I'm going to disconnect the spots for the moment & later on add a relay & a feed from a separate fuse. There are un-used fuse ways, so I should be able to use one of those.
