SwEm Technical Bulletin Number 3  01/03

Attention All P1800 Owners:

Replace your fuseblocks!  (Please note underlining and Bolding)!

The original poor Lucas design, combined with years of corrosion, will lead to continuously deteriorating electrical connections.  Initially the poor connections may only cause nuisance problems (rightfully attributed to "Lucas, the Prince of Darkness"), and the heat generated due to resistance heating will be able to be safely dissipated, but at some point (determined by the conditions in which the vehicle is stored and driven), the heat can cause real damage including an electrical fire!

In my opinion, replacing your Fuseblocks is not an option!  It is required, especially when performing an Alternator upgrade, to safely handle increased currents available from the Alternator!

Fusebox fire! [1800]
posted by someone claiming to be Dave on Fri, Jan 10th 2003 at 11:42 PM

I just had a problem with my fuse box. The fuse was not blowing but it was getting so hot that it was starting to smolder the fabric wire jacket right above it. It was the acc. circuit so the wipers and fan went of. I have not had a chance to look at it in the light. In the morning I'll give the thing a good cleaning and do something about the flammable wire jacket! Anyone have any additional comments?
Thanks
Dave

I hope "Dave" takes my advice before he looses the car to a fire.  Ron
