Subject: Re: Which Optima for starting battery?
Content-Type: text/plain; charset=us-ascii
Hi Stan - I didn't notice any replies to your post...
-----------------
They've found out how cantankerous I am about _________ up a Westy.
-----------------
I agree with everything you say!
Very strange for me to ever admit.
I've resurrected about five Westies and wrecked out about the same number
of Vanagons for parts and in every situation involving double batteries,
added solenoids for the starter I've found burnt wiring, fried
alternators, bad ignition switches and just in general a potential
meltdown situation.
I've also found heavy duty truck batteries under the rear seats with huge
welding cables attached to solenoids under the van along with two or
three real ugly holes in the dash for additional switches.
All in all------- if it ain't broke don't fix it.
I'm not smarter than any German engineer and I just can't fake it.
Double batteries are great!
If they are in there and working properly.
Optima are Great! if you need one.
