Subject:      Goofy CB + Coolant LED Stuff! (sorta friday content)
Content-Type: text/plain; charset=ISO-8859-1

Hi all.

Bernie and I are on the road having a great time.

Just left camp this morning and was heading uphill when.....

Blinking coolant LED! Ack! (this was a self installed WBX relay/etc)

It would go on for a few seconds, then off, repeat. I alerted Bernie
via CB. (The one I installed yesterday and connected to the aux.
battery system) I had also installed a short magnetic base antenna on
the dash. (works fine for short distance btw. Easy to take down)

Didn't panic as I had checked the engine bay this morning. I knew
there wasn't anything wrong with the cooling system. But...... it kept
blinking.

Pulled over. Found that when I keyed the CB, coolant LED would go on.
Huh. Disconnect antenna, light stopped blinking. Huh. Figured it was
some kind of current draw affecting the WBX relay (fridge was on DC
etc.). But this didn't really make sense. Anyway. Decided this wasn't
a big problem and we continued on. STill puzzled.....

I'm thinking maybe my self installed supply line from aux battery to
stock fuse panel was some how involved. (really how could that be???)
Then....

Thought since I had plugged in my DC personal fanto the ciggy lighter
this morning, it might be involved. Unplugged it, problem gone.
Reason: DC fan cable was picking up RF from the coax cable!

Is that goofy or what??   ;)

Neil.
