Hello,
Do you have a volt meter to test something with?
Ask Your Own Hyundai Question
Customer reply replied 2 years ago
yes
Hyundai Mechanic: Virtual Wrench, Hyundai Mechanic replied 2 years ago
Good deal!
First i need the static charge off the battery. Connect the meter and record the reading.
Then with meter still connected to the battery, attempt to start it and see what the volts drop to and record it and let me know both readings please.

Customer reply replied 2 years ago
the static charge is 12.25vdc
after I turned key to start dash board lights went off again ;voltmeter now reading 12.35vdc
Hyundai Mechanic: Virtual Wrench, Hyundai Mechanic replied 2 years ago
Was that 12.35 the reading while the KEY WAS HELD into the start position and you looked at the meter?

Customer reply replied 2 years ago
12.35 reading is in both times : key in starting position and removing the key
Hyundai Mechanic: Virtual Wrench, Hyundai Mechanic replied 2 years ago
HI,
THIS SURE SOUNDS LIKE A CONNECTION PROBLEM EITHER AT THE BATTERY CABLES.
HAVE YOU REMOVED BOTH CABLES AND MADE SURE THEY WERE MAKING A REAL GOOD CONTACT WITH THE BATTERY POSTS? iF SO, DISCONNECT THE CABLES AT THE OTHER ENDS AND CLEAN THEM REAL WELL. ONE GOES TO THE STARTER(POSITIVE) AND THE OTHER ONE(NEGATIVE) GOES TO THE ENGINE BLOCK FOR A GROUND.
AFTER THEY ARE REAL CLEAN AND MAKING 100% CONTACT TRY IT AGAIN AND LET ME KNOW PLEASE.
THIS MAY ALL SOUND ROUTINE TO YOU BUT WHEN I CANT BE THERE I HAVE TO START WITH THE BASICS.

I checked both connections (pos. and neg.) at the battery and both conn. at starter and engine bloc --all are very very clean
and tight .Electr. power came back to the dash board and acssessory ( power windows,head lights...)as if timing relay had
cut the electr. power and after time (20-30 min.) reconnect it like a magic .But again, as ign.key goes to starting position
electr. power is still on untill I depress the clutch switch ,that is when electr. power cuts off totally and volt meter reads
.1 vdc higher .
Customer reply replied 2 years ago
I wander if there is a computer device that cuts off the power and re connects it for some reason?

Customer reply replied 2 years ago
No I have not and it did not even think about it-it did not make sense to me!
Hyundai Mechanic: Virtual Wrench, Hyundai Mechanic replied 2 years ago
Well you wouldn't think so but none of this is adding up so i thought you might try and let me know.
