heres one 5.6 amps
Amperor 12 V LCD TV Stabiliser DC Supply + 3 Adapters | eBay
that one looks pretty good,plenty protection
This one is only 5 amp so maybe the 11 amp one is the one to go for.
Thank you your time and effort it is greatly appreciatedc:
I remember these on the old cars,if memory serves me right they click on and off as the relays kick in and out.
the next 2 look good and easier but I would need to cut the output plug of and work out which is the positive.
Yup, remember to test both with power before you cut them, Ive been caught out like that before, but I would never admit it
