Re: Fan Fail Relay

Gus - I have given the article to several people over the years. The 
only real changes I have made except for a few language changes was 
to add the following disclaimer. It applies to all of the articles 
that may be floating around.

DISCLAIMER

The discussions and modifications described in this paper are not 
warranted or guaranteed by me, Harold McElraft, in any way. The 
descriptions and instructions are not guaranteed to be completely 
accurate. Although I have read the paper thoroughly and attest that 
I have performed the modifications herein described to DeLoreans I 
own or have owned, and others, there is no assurance that I 
described the modification procedures correctly in this paper or in 
the diagrams.
Automotive electrical systems can be very dangerous. Improper 
procedures and/or errors can lead to major property damage, serious 
personal injury, and even death. Only those who are qualified and 
familiar with automotive electrical systems should attempt to 
perform any of the modifications or procedures described in this 
article. If you attempt to do them, you do so at your own risk. 

This article was originally written around 1985.
