I have just swapped my trusty and rusty 4600 for a 4610. I need to sort out various niggles (like a fuel gauge that doesn't work - you can't see down the filler like you could on the 4600 - and various lights that don't work). I have a couple of basic manuals for the 4600 and 4610 before 1984: but the 1987 4610 has some changes. Can anyone suggest where I can find a workshop manual online - or, particularly an electrical diagram for the 4610?
