Note that fuses “blow” due to an excess of current, not a break in continuity. It seems likely that your power socket (or the wiring in general or some other connected item on that circuit) is causing an intermittent short circuit, which could be simply connections or wires that are out of sight, touching earthed metalwork due to the item being insecure or wobbly or worn. I would inspect closely, as soon as. Yes, but "an excess of current" can also be caused by a loose connection. The loose connection causes a voltage drop, which results in an increase of amperage...

Belle has a leaky oil seal on the rear n/s half shaft. So I drove her with the bits to my trusty local garage who will also fit new brake shoes & diff oil (they need to drain the diff anyway). A bit too big a job for me & my skills. Probably a bit late to say this John but put Redline LSD oil in mine which cured the clicking of cone clutches in my BTR diff when manoeuvring on full lock, particularly in reverse. This stuff, but two bottles needed leaving you with some spare. ![[Linked Image]](https://i.ebayimg.com/images/g/yZQAAOSw2FVbSH-W/s-l1600.jpg) Not too late the local garage couldn't get the splined wheel coupling to come off the half shaft. I taking it to Allon Whites in Oct. On the plus side the local guys said no charge as they couldn't fix it.

Sorry, but I don’t think Georg Ohm would agree, if he were still alive!

They can be an absolute sod to split, AW will have the appropriate puller for splined hubs & perhaps a gentle blow over with the gas axe Hope you get it sorted

Doug is correct. Sorry but back to physics classes I'm afraid ![[Linked Image]](https://www.series2club.co.uk/new_forum/Smileys/wittsends/znaika.gif) A bad/intermittent connection provides an increase in circuit resistance which does cause a voltage drop at the connection point, but by the same token a reduction in circuit current. I = E/R

Had a heavy duty hydraulic splitter on mine for about 48hrs and extended up splitting the end of the axle and snapping the nut in half... In the end, removed the half shaft and took it to the Bellengers. They have a massive industrial traction engine hub puller. They stuck it on, but no joy. Then a load of oxy, but no joy. Then the sledge hammer can out. After much heating, pulling and smacking it eventually came free. Turns out the previous 'restorer' had put the woodruff key in the wrong way round. Then discovered that the wheel studs had been fitted akin to an earthquale in a graveyard so ended up getting a replacement half shaft and hub.....

I = E/R I suspect there may be some logic in the thinking that a loose connection causes a rise in amperage, in that heat can build up at the location of the loose connection, to the extent of causing the wiring insulation to burn causing all sorts of mayhem in houses factories and Morgans too..! However as Richard pointed out ohms law rues and in this case the logic is flawed.

Fingers crossed it was installed properly and obviously you don't have to worry about the wheel studs

Well, then, there must have something else going on because I have solved tripping breakers on a couple of occasions by cleaning/tightening loose connections...
