harvestmouse Posted July 17, 2011 Share Posted July 17, 2011 Spitfire 1500Ok, this may sound like a silly question if you've already found the oil hole on your diff, but I can't find it! This may be due to the whole thing being caked in gunk.Presumably it's a square thing rather than a hexagonal bolt head, but if someone could give me a clue as to whereabouts to find it, I'd be most grateful. I have to work next to the road, so the less time I spend with my legs sticking out into the traffic, the better.If anyone has a photo, that would be even better. Can't find one on google that shows the oil top up and even the Haynes is vague about it.Thanks very much in advance. Link to comment Share on other sites More sharing options...

harvestmouse Posted July 17, 2011 Author Share Posted July 17, 2011 Oh and whilst you're here, how about this one?The rev counter stopped working. Then I put the brakes on and it worked again. Release brake pedal, no rev counter. Apply it, rev counter works. Ten times in a row, so not a coincidence.Later on, the rev counter stopped working altogether.The wipers also worked intermittently...... at times when they stopped, I pressed the brakes and hey presto, working wipers.This is a head-scratcher. No doubt a loose connection, but which one, where and why? Link to comment Share on other sites More sharing options...
Dannyb Posted July 17, 2011 Share Posted July 17, 2011 Make sure your earth straps have good clean connections. I had that onceon a Escort where I operated the clutch and the head lights dimmed. The engine was not earthed. Link to comment Share on other sites More sharing options...

Also is the fuse box screwed to the bulkhead?If the battery moves back or the harness moves through the fuse box , it could be moving loose terminals at the fuses, hence the intermittent workingsTry wiggling the fuse box with electrics on Link to comment Share on other sites More sharing options...
harvestmouse Posted July 20, 2011 Author Share Posted July 20, 2011 Is your battery fastened down well? Double fixing. Gravity and prayer.Also is the fuse box screwed to the bulkhead? Think so but will check.If the battery moves back or the harness moves through the fuse box , it could be moving loose terminals at the fuses, hence the intermittent workingsTry wiggling the fuse box with electrics on Will do.Have only just acquired the car, so there are no doubt going to be some niggles.Thanks all for your help so far. Will update progress. The engine earth strap seems ok, but it's worth cleaning the contacts. Still can't understand why touching the brake pedal made the rev counter work....

Richard B Posted July 20, 2011 Share Posted July 20, 2011 Make sure the earth wire is attached to the revcounter. Sounds like its earthing through the brake lights. Link to comment Share on other sites More sharing options...
harvestmouse Posted July 28, 2011 Author Share Posted July 28, 2011 Diff oil now done. The filler is fairly obvious when the gunk is scraped off.Fusebox fixed ok. Battery cables ok. Will check for loose earth wire on rev counter next. Considering the lack of space under the dashboard, would it be easier to remove the counter by removing the knurled nuts behind it and then check the wiring? Did a dashboard change on an mg and I think it had the same instruments.Can move the earth wire or add another one if I can't see where the other end of the wire is.Thanks again to all for your help.

aar0sc Posted July 28, 2011 Share Posted July 28, 2011 When topping up the diff does it have to be on the ground and level? Link to comment Share on other sites More sharing options...
