Jumping Batteries

Mixo, I would be worried if you need more cranking power then the jack can provide you?? If so I would check with Rotronics if their system is compatable with a gel cel, or Odessey batt as the main, with more CCA!!

What rotronics system are you running?? I cant see why you would ever want to get rid of it, as some have stated, they are top quality, only wish I could afford!! I cant see why you couldnt jump the Aux battery for a temporary solution to a cold morning start but not permanent with the Rotronics fitted, would sort of defeat the purpose of such a good system!

But yes jumpers from batt in parallel will certainly allow you to start and should not evffect it at all!

Do you have the rotronics CD, it shows the circuit diagrams for all the systems they sell and the cd is free! Just give a buzz and they send it out!

Goodluck, Matt.

Mixo, if you are having trouble starting on very cold mornings, check out the previous forum posts regarding t/d jacks. The culprit is the engine oil being too high in viscosity and low in quality, you need to run a 5w50, or 0w40 grade fully synthetic oil. the previous posts will keep you reading for hours. cheers Brad

Yes Bob - agreed - one pos lead should do the trick for jumping. I have been pretty careful with the quality of fittings and installation so battery earthing should complete a good circuit. On the oils Yarda, that is a long story as you say and I have contributed to quite a few of the posts you mention - I have settled on 10w-40 as my "norm". 95% of my driving would benefit from that grade, and I "takes my chances" with the cold snaps. Seems to me that the 0/5-30/40's are getting too thin for prolonged use in mild conditions. By the way, spoke to an owner trucky the other month who runs conventional oil in his Cat TD's for 25,0000 intervals. Does not believe the synthetics are worth the extra dollars.... hope he's right....lotta dough at stake there.Gotta have red sand on those boots !
