Greetings

I bought a 99 Accent last October 07 and about 2 months later I started to get these surges where the lights would brighten and I would loose power until the surge dissipated. I would last for about 2 minutes. I've had it checked by a large chain store here in Canada three times. Done diagnostics - no problem. Had new battery, plugs, wires, and a coil replaced still have the problem. Recently had fuel pump replaced. Still have the probem. It's becoming more frequent. Any guess. I thought it might be the voltage regulator but someone on another forum said the North American models don't have one. Any answer at this point would be greatly appreciated

Thanks for your time and attention

Hi hinoon,

Thank you for the donation.

All vehicles will have a voltage regulator. Only difference is the location, some outside the alternator while others have it inside the alternator assy.

I would sugggest
1. Testing the charging rate of the alternator to see if it is correct.
2. Check the pulley dynamic damper for fault if equipped.
3. Check the groundings straps.

Does problem reoccur after it goes away?
When it surges, what was the engine rpm?
How often does it happen?
Longest period it does not occur?
Engine temperature?

Thank you very much for your response. This problem has been nagging me for almost a year. But it still run.

Does problem reoccur after it goes away? Yes

When it surges, what was the engine rpm? 3200

How often does it happen? Every day.

Longest period it does not occur? Depending on the drive. Maybe 20 minutes. When I'm driving on the highway at 60 or so it doesn't seem to occur.

Engine temperature? Dont' know where to look for that.

Engine temperature = meter temp gauge.

If possible, I would suggest attaching a volt meter and check/test when the surging happens.

Is the engine able to rev up when no load?
