Same hard to start prob...with new twist.

[J-Man]

Alright been battling same problem as most on this site....viewed/seen and executed
most remedies that people have submitted. But still have same hard to start problems
with a new twist to it.
All lights go dim and battery needle drops all the way down, when I floor it or accelerate getting on the freeway....but then let off throttle maintain a 70mph and after a minute or so,...bling bright lights again and battery needle goes right back up.
Also if I stab the throttle off the line sometimes chokes.
All this is very strange.
I have all new....
RPM 180 Alt, High tq starter, optima battery, just changed new power cable to battery along with new purple wire, have new plugs, wires, and rotor cap. coming in next week I have new coil and relay that I will try.
Is there anything else?....geeezz.

Sounds to me like either the seat prob. or a bad alternator.

Its a Syclone....
and don't have a datamaster yet.
Its a brand new ALT from RPM less than 2k on it.

From left field: Motor mounts are broke, when you stab it motor rocks and something is shorting? Check the term block on firewall. Power brake it with hood open and see if motor moves when it stumbles. Check connections at alt. Check bat ground; rear of pas side cyl head.

I'll check the motormounts this weekend. I guess that is possible about shorting something.
I'll also check but probably just replace the Battery ground.
Thanks for the few more ideas..

Re: Same hard to start prob...with new twist.

battery ground would be first thing.. I also think mounts would cause, happened to my s-15 jimmy a while ago, This sounds dumb, but loose belt?

Re: Same hard to start prob...with new twist.

Checked the torque of the motor for broken mounts ...looks normal, good.
Checked the Battery ground....everythings tight, good.
Belts nice and tight...all conections are good, no loose wires.

Figured out stabbing the throttle on low battery causes stumble or loss of power. Good charged battery no stumble.
So, I actually think my new (6 month old) optima battery is the cause.
It dosn't hold a charge, recharged..... drive 10 miles completely drained.
Took it to AutoZone to get replacement they have to test it first, so will find out tomorrow. All wthis and it comes back to the battery? Weird. I wonder why? Well we'll find out tomorrow. Will post findings as they arise.

It helps to have a solid understanding of automotive electrical theory, or enlist the help of someone that does...

......SO....Dave, you busy this weekend? :lol: Where are you located? I'm in Orange County.
Your on to something...I will definately investigate my wiring set-up. Don't have much time to enroll in an automotive electrical theory class right now.... but, if I know someone who does (Dave) maybe I can get their expertise. :tup:
