Improve Engine Start Wiring
-
The dirty little secret here is; the GMC starter draws 100 amps just to run,
and 300 amps to crank the GMC. This says that any connection between the
battery and the starter (say.01 ohms) could drop 3 volts. A few of these
will cause big problems.
The OEM connection of the starter to the Boost switch was"just ok", when the
GMCs were new. but now, with Owner changes ( cut-off switches, bad cables,
bad grounds), use of the boost switch and hard starting have become common
complaints.
This is a simple 2 step process to help remove these problems - for free-.
You can leave in your disconnect switches, random wiring, etc , just hook
the starter and engine directly to the battery. The cranking is safe, full
proof, and will not drain your batteries in storage. So there is no need
to disconnect the cables when the coach is not in use.
An interesting side note. Mr.C and my favorite saying is " ask 3 GMCers a
question and you will get 5 answers. So when I gave this talk at GMCWS, I
asked how many were going to rewire their starters----- none raised their
hand. But just after the rally 3 have called me to say they made the
change and saw a real improvement ;>)
so do your own thing, but keep this in mind when you reach for the boost
switch
