None technical rating needs help...

Hi all.

Am having non starting issues and am learning as I go.

Bongo was good for the summer and a few trips out of Scotland to Englandshire. While last away not starting first time. So changed glow plugs. Long ones for short one after two weeks, guess what... Rubbed through isolation and shorted.

So new glow relay in.

I drained the battery from trying to start so much. Got a Bosch S4 Car Battery 335.

Replaced glow plugs again Correct size this time.

Then fusible link issue wire was burned out. Could not order one locally so did the fix of wire and fuse holder.,some of you will have seen the pics from someone that dud the same.

So replaced relay, right glow plugs, battery, and fusible link 30 amp fuse.

Started fine 1st time, great took her for a drive. Stopped twice no issues on restart.

Got back from work today gave it a try, non starter. 30 amp fuse in fusible link blown, only had 2 x 35 amp fuse at home. So gave that a try blow first one. Second one started fine but fuse blown also.

So I think I have short. I could just put in a higher rated fuse. But there is issues there... I could carry 35 amp fuses with me.

So has any one had similar issues and how do I find a short?

Any help appreciated and thanks for reading such a long post...

Sounds very much like you still have the busbar shorting out on the engine to be honest.
It just needs a visual inspection, the Shop should still have the fusible links in stock, they won't pop as quickly, but they will pop if you have a short!

OK I will check tomorrow after work. But with I put insolation tape on the worn bit and with the right size. Was no longer touching pipes.i will double check and let you know. Thank you dave

I doubt tape will work, the heat from the engine will melt it, you need to actually create a gap, then tape it up, but the physical gap is important to prevent rubbing and heat transfer.

Long plugs are now in place so bus bar is raised.

But I have put a 40 amp fuse in and it's not blown.

So do I look for a short or leave it?

Have you been using standard rather than Slow Blow fuses ? If so this might explain the problem without a short being present.
The initial surge of current is significantly higher than the running current hence why the fusible link is used, Slow Blow fuses aren't ideal either as they are normally only in the region of 50-100ms. The fusible link is an extreme type of slow blow taking 2-3 seconds of 60-100 Amps before blowing.

Get yourself a fuseable link and remove your inline fuse.
