Golf MkIV fusible links

[Geoff Ashcroft]

One of the 50 amp fusible links has blown on top of the battery (2002 MkIV Golf 150GT TDi) and I'm having trouble working out what it powers.... It's the second in from the right hand side if anyone can shed any light on its purpose. I know its not the rad fans, as that's a 30amp and been replaced before along with a control module mod. Any help gratefully received, so I can hopefully track down the cause......

Handbook or what's stopped working?

[Geoff Ashcroft]

Handbook only shows fuse board and relays inside r/h end of dash. Process of elimination hasn't shown anything yet, as I'm still working through it....just a matter of time before I track it :-)

Don't know if this helps you or not. Borrowed from the R32OC site. It looks like it could be the glow plugs.

Thanks Bob - it was indeed the glows. Fooled me to begin with, as the glow light illuminates on the dash, but power never went through to the plugs. Good job the weather has been warm, or I'd have been reaching for the easy start (though I'd have found the problem much quicker, I guess).

Glad you got to the bottom of it
