    For the last couple of weeks the temperature has dipped below zero (Celsius) over night, and the Burb has been getting tougher to start. This weekend it just wouldn't go anymore, and I dragged the batteries in for a charge.

    Before I go out and get a couple of new 1000 cca's...

    What do you guys run for batteries? Anything fancy? D4's? Deep cycle? Any tricks?

    I have 2 Durabast 1000 ccas. What size are your current batteries? What condition are they in?

    Did you try plugging the block heater in? It aids alot in cold starting.

    Glow plugs working correctly? What kind of GPs do you have in there? Is the glow plug timer working correctly? If manual switched do you leave them on a bit longer since it is colder outside?

    How is the starter? Good shape? Used alot? Are you letting it cool off between cranks? I think its after 15 sec of cranking a 3 min cool down time before trying again.

    Is you cold advance switch and other things of that nature up to working order?

    What size battery cable do you have running from your passenger side battery to the starter? 2 guage is good but I went to NAPA and got me an 0 cable. It seemed to help alot on those cold winter days. My batteries have top posts as well as side posts so I could use this cable. They said it was for welding!! /forums/images/graemlins/eek.gif But after 2 sets of batteries and 2 starters I didn't want to have change it all again!!

    Are you holding the accelerator down a bit further when you try to start it since it is colder outside, per the directions on the back of my drivers side visor?

    Any questions?

    Get the highest amperage cranking battery you can get. DO NOT USE DEEP CYCLES. Simply put, deep cycles are meant to deliver a small amount of amps over a long period of time, while cranking battteries are meant to deliver a large amount of amps over a short period of time. Deep cycles are also designed to be completely drained and recharged, over and over.

    Optima red top batteries are widely popular, but rather expensive. I've been using Everstart Extreme batteries from Wal-Mart with good success.

    Lets see what I can answer here...

    Two Magnacharge 850cca's. Dunno how old - they're not dated, and I've had the truck for a month. Stock battery cables - whatever they are - looks like #1 or 2. I hooked them up a battery charger and plugged in the block heater overnight. Started instantly! Warmed up quick too, although it didn't make any difference when the batteries were low.

    I'd been doing the crank 10 secs, wait 30 secs, as per the shop manual I have.

    Starter looks recent, and with the strong start today - can't fault it for anything.

    I do notice the glow-plugs cylcle for longer now that its colder. I checked out the controller, and it looks like it's been replaced recently (not gungy yet). I don't really want to do the manual override business until I put fresh GP's in.

    Cold advance switch - hmmm... time to read that shop manual some more! /forums/images/graemlins/blush.gif

    I've try the part-throttle in the future... my visor has no starting instructions /forums/images/graemlins/tongue.gif

    Maybe I'll go shopping for some fatter cables. /forums/images/graemlins/smirk.gif

    Thanks for the info guys /forums/images/graemlins/thumb.gif

    Okay.... I found out the hard way what the problem was - after getting stranded /forums/images/graemlins/angryfire.gif

    Had to parallel up THREE 1000 cca's, fingers crossed, and it just barely spun fast enough to start. /forums/images/graemlins/eek.gif

    Got home. Hauled out the starter. Damn thing looks like it came out of the box yesterday /forums/images/graemlins/confused.gif There must be some pretty lame jobbers out there.

    I put in a newer gear-reduction type this time. Wooooo... starts nice now /forums/images/graemlins/grin.gif

    Yep, there's a lot of bad starters out there. A few years ago, I bought a lifetime warranty Ultima reman starter for my '81 for a $100. It's a good starter, but I have to replace it every year (at no cost to me--under warranty). One of these days I'm going to try the GR starter. Do you like yours really well? Does it spin over really fast?

    Three 1000cca batteries? Wow....thats alot of power!!

    Glad you found your problem. I would also suggest while you are under the hood to change your battery connections to Dr. Lee's battery connections. Much more reliable.
    You can find them at http://www.thedieselpage.com

    The factory starter (at least my almost dead one /forums/images/graemlins/grin.gif) can't hold a candle to the GR.

    My estimation is 2x faster and has a distictive "vrooooom" as it spins down. Mine was from a '99 Savana 3500 van - cost me $200 CDN (tax incl.) w/4-month warranty from the boneyard.

    Not cheap, but I can't deal with a starter that's going to pack it in yearly /forums/images/graemlins/crazy.gif

    The Gear Reduction starter is THE NUTS for my 6.2. I've torture tested it by excessive cranking (for weeks) when I didn't have my air leak fixed /forums/images/graemlins/blush.gif The GR starter is still going strong. /forums/images/graemlins/thumb.gif

    Also, why you have your starter out, replace your battery cables with #2 or #1 cable.

    It cost me a total of $60 to replace all of my cable with weld cable and ends, but DAMN, it cranks!!!

    I noticed at least a 50% increase in cranking RPM's with no other changes!!! /forums/images/graemlins/eek.gif /forums/images/graemlins/eek.gif

    I agree, it's the first thing I do on every vehicle I get, not just Diesel, gassers too.
    Make a hell of a difference

    Where did you get your starter and what did it cost?

    My '89 came factory with a GR starter. I'm not sure when GM started installing them on 6.2s. I also bought one on Ebay cheap, ($50) couldn't pass a good deal /forums/images/graemlins/grin.gif I would imagine they are kinda dear, new /forums/images/graemlins/eek.gif

    I paid $200 CDN for a good used one w/120 days warranty from a '99 Savana van.

    I could probably have done better shopping around, but I wasn't about to turn the truck off that night without having a good one to put in /forums/images/graemlins/rotfl.gif

    Well when I was in the Middle east and I had problems with my starter, I got #4-0 but I also relocated my battery to inside so I added 4feet to the length, and still it was overkill.
    Now I use #1 for 3feet or less, #2 for 1foot, and only use the #0 when going 4-8feet.
    I would still use the #4-0 if I want to relocate to the rear becuase it will be closer to 12feet. /forums/images/graemlins/thumb.gif
