Default igmition start problem

Hi I decide to open a new thread. about my starter problem. since I just get new information about the problem.

ok here are the facts

turn the key on the ignition nothing happed
I all ready take the starter motor to a shop to check. 2 times. and the starter motor is OK

battery is new and have 12.5 v at rest. and 12.2v at load

I remove the starter relay and make a direct conection. since my VAT system is gone.


here is the test

yellow wire from ingition swicht alon give me a 12.4v when turn the key

but if I conect to green wire that go down into starter. I get 11.7 v.

every one knows if I dont get at list 12v the starter motor wil not do nothing.


my question
why is when the yellow wire coming from the ignition is disconected. I get 12.4 but if I conected to the green wire that go to starter motor I get 11.7

if Iam not clear with my explanation letmeknow and I will try to explaind better

Where are you seeing the lower voltage?
At the starter motor?

the trigger wire coming from ignition show only 11.7v
I trace the problem back to the conection where yellow wire coming from ignition switch and join with the green wire going from gear selection switch

if I disconnect this 2 wire. the yellow wire have 12.4v and the green wire 0v dont know why when I connect this 2wire the voltage drop to 11,7v

How did you get a Corvette over there in Panama? Must be an interesting story, for another time.

I can't offer help on the level that a lot of the other guys can, but I just recently got my car started after having it sit for 6 months!

My initial problem was the fuel pump. After replacing that, I still had starting problems. I couldn't even get it to start. It seems to have an MAF problem now, but it does run and drive after I swapped all my fuses! I have had that happen more than once, three Corvettes later! Many of the no-start problems turned out to be fuse-related for me. THEY LOOKED FINE, but I replaced them anyway...and more than once they have started right up! Anyway, worth a try.

Have you had the cranking amps checked on the battery as well?

Again, I don't have the know-how that a lot of these other guys do, but if nothing works I am sure someone will come around.

Only other help I can offer is that if you think you need a starter and can't find one over there, I do a lot of International shipping and I live right next door to an auto parts store...so if you can reimburse me I would be willing to try and help get you a starter. I am not an auto parts dealer, but often ship around the world for business reasons.

It's a crazy world out there these days, but it's just an offer.

Good Luck!

Thank you for your advice. About the fuse. Dont think thas a problem here. Since the wire schematic dont show a fuse in the area iam talking about. Battery that came to mind. But before i get this new battery. I recharge the other one so many times . Thinking that the battery was the problem. And never solve the problem.

Need to know the reason for the voltage drop. When wire conected to the sarter motor.

You said you had 12.4 going into gear selector switch and 11.7 going out. Bypassing the switch would help you know if the switch is at fault.

you can usually go down to bout 9.5 volts to the starter and it will still spin, your issue seems to be that its not getting energized

No. Before the gear selection swich i get a drop. Where the yellow wire meet with the green and white wire

Yellow wire coming from the ignition swicth. Meet with green and white wire before going to GEar selector switch. When i connect this 2 wire is when the voltage drop. Dont know why i get a drop. In voltage. Just by conectin 2 wire

Hey, you're welcome.

I gotcha...I need to get better at reading schematics. I do it a lot with guitars and amplifiers. Guitars are okay, but amps are tough for me sometimes. A lot of the time I do things hands-on, and that can be time consuming. Most the time it is something simple though.

My car does not get a lot of use. Just a pleasure cruiser really, so I bought a charger for it. It works well, but does not read cranking amps, so that came to mind. It didn't start when I charged it this time, so I brought it to the auto parts store, and they checked the amps. They were within specs, so that wasn't my problem either.

Sounds like you're analyzing it the right way, and I see you've got "Agent 86" on board...You're in good hands.

Good luck...I'm sure you'll get her going again...
