30Amp Fuse Keeps Blowing

[StevenN]

Hi all

My Surf has been stood for a few years. 

Ran it a few times just to make sure it started but must admit it’s been about a year since I last tried. 

Anyway I had to move her so I fitted a new Battery as the old one didn’t have enough umph 

But when I have fitted the new Battery the Pink 30amp fuse keeps blowing. 

I have tried disconnecting the big lead from the starter motor but still no joy

Any ideas of what the fault could be or what to try next?

Any answers appreciated 

Cheers

Steve

Just a thought have you checked all the wiring in case squirrels have been chewing and nesting in there somewhere.

HI TP49

The car was stored in a garage

 No signs of any rodent infestation 

I have a window open just in case I couldn’t unlock it

Everything was fine when I was trying to jump start. 

The fuse popping only started once I had connected the new battery 

However I will have a check for anything out of place or chewed

 

Cheers

alternator alloy corroding from inside out causing short across its body or its diodes? is it the charge fuse? try disconnecting alt wires anyway to rule it out.

if not check the scuttle panel for build up of leaves etc and filling up with water

Hi Robster

I will have to give it a try

The alternator was fairly new but that’s not to say corrosion hasn’t taken place

Another snag is that the replacement fuses I had ordered are stuck at work

I May have to try to get another batch delivered 

cheers
