Jump Starting

[Jason 91]

I've been traveling quite a bit this winter and very busy when I'm home so needless to say, the ZR-1 hasn't been driven much.

Surprise, surprise, I have a dead battery. :icon_scra

I do not take even the simple things for granted on this car so any issues/concerns/special tips to jump start this thing? I plan to follow the normal procedures and it looks like the best place to attach the negative on this car would be the frame directly beneath the upper radiator hose.

Thanks,

Jason

I am going to JUMP START this server in a bit.....using my Z 12v battery.

I will connect the Z 12v battery directly to my router.

Are you ready Z Factor?

WOW.....now several hours later after I hooked up my Z 12v battery to my router to attempt a jump start of this server (blew the damn router to smithereens and am now on dial up) this server is now (at least for these few minutes) performing at great speed :thumbsup:

I disconnect negative battery cable
whenever the car sits for long periods. I think it also helps cut down on electrolysis.

Great point :thumbsup:

Some others try the trickle chargers but I am not sure if they actually extend battery life or not.

I use a Ctek 3300 float/pulse charger - thing rocks and you can get them $60 shipped on ebay. It absolutely extends the life of your battery and is extremely easy to use.

I prefer to never jump a car unless its absolutely necessary. If I do jump it, its not from another vehicle, its from a portable Jump starter battery.

My preference would be in this order:

1) Charge
2) Jumper Box
3) Cables

Charging the battery is the safest approach. Odd things can sometimes happen to electronics particularly if you hook up the cables wrong etc or voltages spike. There is a slight risk when you jump and electronics are expensive and tough to troubleshoot. Your risk is zero if you charge the battery.

My only exception to your informtion is that I carry jumper cables in all my cars/trucks including my Z which means this is my first choice on the road. I have used them often with great success including the jumper cables in my Z. I would have to say however, that my most often used choice in my garage is to charge the battery with a battery charger :thumbsup:

If a dead battery is a repeat occurance, I would check the battery for BAD cells using an inexpensive battery hydrometer (the one with 4 floatable balls of different density). As the battery discharges, the specific gravity of the acid diminishes. A fully charged battery will float 4 balls.

If your battery is a sealed battery this method will not work obviously since you cannot get to the acid :happy1:

In the latter case, a load test of the battery will tell you the condition of the battery. WalMart for example can perform a load test (battery out of car) :thumbsup:

If your battery is dead, it's probably better to put a charger on it than jumpstart the car. If you jump start it, then the alternator is going to have to strain to charge a dead battery. If you charge the battery first, it won't, and you won't have to jump it.

I won't argue your point because I've used cables as well with good results. However, in my opinion if you want good cables that work well, they should be thick and often run about $50. You also now need to find someone to help you with a jump. If you shop around and get on a sale you can get a really nice jump box in the $80 range with good cranking amps. You are then self sufficient. I also bring mine on my boat so it serves double duty for me. Sometimes different trucks/boats are on different voltage systems which can also cause problems with electronics.
With using you charger or charging box, you can control the variables. Charging is also easier on your alternator and if you are going take the car somewhere, its better with a full charge on it then just a jump because unless you are not going shut the car off for a long time, the alternator won't have enough time to recharge the battery.

Thanks for the feedback on this. :cheers:

I actually hooked it up to a charger last night and am monitoring it. I will probably just disconnect the battery from now on since I do not know when the next time I will drive it will be between the snow, the cold and my frequent travel back to NY.

For those of you in warm climates, I envy you! :-(**|=

If you are forced to jump start your LT5 with jumper cables, where do you connect the negative jumper cable to a good grounding point in the engine compartment on an LT5?

[Racinfan83]

Jason just get a battery tender. I have used this one for 2 years now and it is great. You can probably get one online cheaper if cost is an issue...

Thanks Racinfan83. I already have a battery tender.

Since I don't carry the battery tender on the road, I was trying to find the proper point to connect the negative ground jumper cable for a roadside assistance. The same holds true for the Jump N Carry unit.

[Dynomite]

Connect jumper cable to Negative Battery Terminal and Positive Battery Terminal.

I do not use battery tenders......I use Battery Disconnect on ALL Zs.

Thanks for the quick response. That was my thought also. My hesitation has been with the warnings in the manual, and procedures on the Jumper cables and the Jump & Carry.

I just needed the assurance from someone that has a ZR-1.

Thanks again.:handshak:
