[Vwpickups] A2 glow plug !@#$! - firewall fuse?

[Mathew Banack]

Thanks James,

 

According to Bentley, there are many different fuse/relay panel layouts.  This particular car seems to have the one on pg 14-36, with a 2-bolt fuse on the top of the relay panel, and the legend says its for the glow plugs.  It looks like the firewall fuse on an A1 deisel and it meters fine from screw to screw.  Thats not to say they could have put another fuse in there somewhere else...

 

I'm familiar with the firewall fuse on my 81 pickup, and I don't see a similar thing on this Golf.  If its hidden somewhere ... @##%!

 

I went to the pick-my-part junkyard hunting for a starter, but only found 1 diesel, and the starter was a gasser-type without the reduction gearing.  I didn't take it.  

 

This Golf has a cracked and cloudy headlight and I did find an A2 headlight, that takes an H4 bulb, instead of the normal o-ringed bulb.  The lens and reflector were nice and clear, and there was a bulb-base halfway up the reflector with a mini-bulb in it like a clearance light.  My curiosity got me, so I paid the $5 and brought it home to look at it.  Anyone know waht that is? 


 

Thanks,  Mathew Banack
