Re: [DML] Re: Fuses

Walt, Your right, It sounds like I'm talking about the fuse block with all 
the fuses in it. What I was trying to talk about is the fuse block, or strap, 
or holders used to replace the fan fail module.Thats where I see 20+ amp 
fuses. If that get's to hot due to overload, and the fuse doesn't blow fast 
enough due to overating then there could be potential problems. Sorry: not 
trying to mislead anyone. I have an eraser on my pencil also. I build and 
will be on the web site soon a plug in modification for the fan fail module. 
guess what, I call it ( The Fan Fail Fix ) Each leg to the fans is fused at 
15 amps to maximize the protection to the $259.00 fans. Fuses are cheap. I 
also use long terminals out the bottom to maximize the contact surface when 
pluged into the socket as DMCJOE is relating to by contacts being tight. 
Since most folks can't or won't take out the terminals to tighten them up, I 
use the long terminals to help compensate. 
Out of the Bussmann catalog: During normal conditions, an overcurrent 
protection device ( fuse or circut breaker) must carry the current without 
nuisance openings, However, when and overload or short circuit occurs the 
device must ( interrupt or blow ) the overcurrent and withstand the voltage 
across the device after arching.
They also say: In the Bussmann catalog, The circuit protection device is 
designed to handle this value under steady operating conditions and at 
ambient temp near 25degree c. It is recommended that circuit designers select 
device ratings above the normal circuit current to prevent nuisance trips or 
blown fuses. 
Since the cooling fans in the De Lorean are an electric motor ( inductive 
load ) and if the motors are in good condition, the 15Amp fuses in the fan 
fail mods offer max protection, will handle inrush current and won't restrict 
current flow to the motors.
If anyone would like the two page ( basic overcurrent technology ) out of the 
Bussmann catalog, I will be happy to fax it to you. 
DMCJOE is also correct in the #7 fuse. The fuel pump in the De Loreans is a ( 
inductive load motor ) which under stress or load conditions draws more 
current and will melt #7 without blowing. The FV is also some what of an 
inductive load device, so when you get both of them going. It's melt down 
time over a period of time. His recomendation of replacement is wonderfull.
Hey, Walt 
Call me.
