I replaced both senders with second hand units and still had same problem, checked the senders on the multimeter and they seemed to be fine. when the plastic screen got cracked last weekend (someone with bad aim and a set of keys) i decided i might just try the clocks while i have them out to change screen. Would be happy to even get a lend of a set to test if anyone has spares? if not, is there any way to test fuel gauge while clocks are out???
