Hi Guys. Below is from one of our DOG members. It is part of a long email about several topics sent to me so I have trimmed it down and passed on the relevant data related to Dimona users. This relates to what he recently found on someone else's Dimona and worth taking note of. The wiring loom referred to and visible in the images is the loom containing the "alternator regulator" feeds. This stuff doesn't go dead by turning off the master. You must also kill the engine as the alternator field stays active with the engine running. A sobering thought. Note if ever confronted with an engine fire, turn of the "alternator" circuit breaker if you have the style fitted that allows you to do that. If not just remember that until the engine stops the alternator is still busily generating current which may or may not be part of the problem.
Fellow DOG'er Quoted thus. "There was damage found to the wiring loom located behind the right air filter. (See attached pics.) Cause was the bolts thru the filter have been installed with the heads nearest the carby which leaves the nut & extended bolt thread poking out the back & there is F%$# all clearance back there. Cannot see the damage unless the filter is removed either. Fortunately the wires that were damaged were earths, so no arcing occurred, but the scenario certainly had some potential for a fire. The throttle rod support bracket on the right carby fouls the edge of the air filter too & this prevents the filter flange from fully engaging on the carby adapter. By relieving the bracket at the point where it contacts the filter you can gain about another 5 mm forwards with the filter which of course gives a bit more clearance at the rear too." I thank him for is comments. This is worth checking as it is easy to miss when assembling the filter assembly. It should only be assembled with the bolt thread end forward. Down side is you can't see the damage. We all know how tight things are back there. So heads up. Check which way round the bolts are. Also note with continued retightening of the engine restraint cables, the engine, over multiple service events, will progress rearward in the hull reducing rear clearance further. The bracket issue he mentions is worthy of note and have seen this but not an issue on all engines. It depends on what part of the tolerance the thing is made. Basically the bracket is a hand made low production conponant and thus prone to inconsistency. Cheers. Nige.
