Update 27 -10 2019 Been a lazy sod, and its been raining so didn't get a chance to delve further till today. (Shame as it would have been a great day for the 'last ride of the season' had I got it fixed. Anyway, tank drained, battery out, tank off, flange out (first mention of flange.....) Out came the pump/flange (second.....) assembly for some meterage....... Wires straight to the pump terminals and off she goes like she is meant to - so pump ok (Have a new one just in case - worth keeping as a spare). Next.....put 12V directly on the same wires outside the flange (getting my moneys worth today flange wise ) and not a sausage. In fact if I do a continuity test between red and black wires its a direct short, which seems to indicate , with the pump working when directly energised) that the wiring harness is at fault. Ho hum, off to order the new loom now - hopefully some sunshine next weekend ..... Can anyone tell me what this items in the picture (red arrow and blue arrow) are? Thanks Daves!
Red arrow could be a condenser, to give the pump a kick when starting. Blue arrow, don’t have a clue.
Thanks Hyper, Figured it might be a capacitor/condensor of some sort, but buggered if I can find it listed as a spare part anywhere......still, don't know if I need it yet...so fingers crossed its ok.
