[Healeys] [Shop-talk] Hooking up a trickle charger to a truck with two batteries and a thermoswitch

[Al Fuller]

Hey Eric:

 

I use the Battery Tender brand of chargers an find their website useful.  If
you go to http://www.batterytender.com/connecting-chargers, they have info
on connecting chargers to 2 batteries in series, 2 in parallel, etc.  

 

Under 2 batteries in PARALLEL, one charger they show:



For 2  12 VOLT batteries in SERIES [24v], they show:

Two Quick questions, 

1- Can I hook up a normal trickle charger to a truck that has two batteries?
If so, how should I wire it?  I'm finding confusing info on the web. 
Do I hook it up to one battery only?   
Do I put the pos on one batt and the neg on the other? 
Do I need one for each battery? 

2- Is there a 120vac themo switch for a trucks block heater?  (so it only
turns on the block heater if the outside temp is below a certain temp?
(what would that temp ideally be?) 

Thanks again all! 

Thanks in advance.
