problem lights solved for now

[MQ SWB]

Another question, I've just replaced my indicator switch because it had melted, I've also just put relays in the high and low beam to help prevent this. Now the fuse holder for low beam from battery to relay has melted, I had a 15amp fuse in it. I replaced it and put a 10 amp fuse in it left my lights on for about 2 minutes and then removed fuse and could hardly hang onto it talk about hot, Can anyone suggest what to do if so please do, Sorry to be a pain in the Ar$e

As above can anyone help

It might help if you told us where you ut the relays and how they are wired up (diagram)? What sort of relay?

What low beam bulbs are you running? Add the wattage of both up and divide by 12 to see how many amps the fuse holder needs. i.e. if 50W low beams then 50+50 = 100/12 = 8.3A.

Most decent fuse holders can handle 30A with no problems. Seems strange that you didn't mention the fuse holders were blowing. If they were blowing I would suspect a short somewhere.

Both relays are 30 Amp wired up as recommended byBush65 in an earlier post, wire from switch to 86, earth to 85, power from battery to 30 and from lights to 87, when first wired up both fuses blew, I changed from 10Amp to 15 Amp in the fuse holder the fuse got so hot it melted the holder

I would check the connections you made to the fuse holder. A dry joint will heat up. It may be a poor connection heating up the fuse rather than vice versa.

Sounds like a possibility. If there is 15A going through the circuit the fuse holder shouldn't heat up much.

Are the fuse holders good quality? What is the wire diameter? Did you use flux or resin cored solder when you soldered the joints?

just been out there having a fiddle and when i have the lights on high beam and disconnect the low beam fuse holder there is no difference in lighting and if i disconnect the power supply to the high beam relay when the lights are on high beam i lose all lights, whats going on with that.

Next, remind me if I'm correct when checking voltage you must be in parallel and when checking amps you are in series with the circuit so an example would be connect multi meter in amps and have one probe on one side of the fuse holder and the other one on the other side of the fuse holder is this correct please let me know

TIA

Snip... Dixie

Nothing wrong with that! Low beam is off when high beam is on.

yep to check the current that is correct , make sure you take the fuse out so that all the current goes through the meter

for voltage you would put one leat to earth (-) and the other to wherever you want to check for voltage

Well everything is now working, basically the problem was me not knowing enough about wiring, thanks to everyone who offered help it all comes in handy.
I have 80/100 globes so basically the 10amp fuse was to small and the fuse holder was only rated to 7.5 amp so now have 30amp rated holders with 15amp fuses.
Once again thanks to everyone for their help
