Fumes in cabin & lights dimming??

RE: Fumes in cabin & lights dimming??
I'm not enough of an electrical guru, but whatever...
The voltage regulator isn't a surge-suppressor. It's kind of an amplifier that feeds back to the rotor windings.
The alternator is controlled by delivering excitation current to the rotor, and it generates power in the field windings. The regulator tries to 'smoothly' control that excitation current, but how smooth? The designers take advantage of the battery being in the circuit to act like a big fat filter. Otherwise the regulator would have to include a big filter. Size, weight, cost, etc...

RE: Fumes in cabin & lights dimming??
Finally solved the 2 problems
The fumes was caused by a crack in the exhaust manifold - new manifold fitted - all ok.
The lights dimming was caused by an electronic gadget called an " electronic load detector" its associated with the fuse box, which also had to be replaced. - now all ok. (The Honda dealer did change the alternator & regulator, but that did not solve the problem)
Again, thanks for your input guys.

Higuys,
I'm new to the forum.
I have a 2004 Honda Accord 2.2 iCTDi estate executive. (UK spec)
Ihave had it for about 6-7 months, on which the first 3 months I had no issues with the car, on the fourth month I noticed a funny smell in the cabin of the car (with the car climate setting on 'auto')It smelt like an exhaust type of smell. When you pushed the climate button to re-circ, the smell would gradually go away. This was really noticeable when the car is sitting in traffic.
I took the car to a local 'kwik-fit' (car exhaust garage) and asked them to check if there were any leaks on the exhaust, on which they checked up to the CAT and said it was ok.
Ithen took the car to my local Honda dealer, who did not appear to be very helpful; they suggested it was coming from bacteria in the A/C system?? They said that the A/C system would have to be chemical cleaned to solve the problem. I said if it solved the problem, please do it. When I got the car back from the Honda dealer after they had cleaned the A/C system?? There appeared to be a very strong chemical smell in the cabin, the Honda dealer said this was normal, and would go after a week or so, on which it did, but after a week the fume type smell re-appeared. When I say re-appeared, it probably never went; it was probably just masked by the chemical smell.
For the last couple of months, I can only drive the car with the climate control, in re-circ
Can anybody help with this??
My other problem with the car, is the dimming of the lights (head lights, interior & rear lights), when the car has the head lights on (& interior lights on) at tick over, all the electrics seem ok, when you gently rev the car the lights dim?? When you rev the car a little harder (say over 2000 rpm) the lights get brighter. Again I have been to my local Honda dealer, who just replies back with the comment 'that this is normal', yet I have never seen any other Honda Accord (same model) do this?? When I bought the car, I fitted a bigger (more amperes) Bosch battery. Any Ideas anyone
Many thanks for reading this problem
Apart from the above, I love the car, & don’t really want to change it.

I have a 2005 Accord 2.2 diesel and also had fumes in cabin. I have discovered that the exhaust manifold is a known problem and Honda have extended the warranty from 5 years to 7. If the car has done under 125,000 miles it should be covered by warranty (I live in the UK) and so all work should be foc. Sorry the reply is about 4 years after the post but when I googled the problem this post came up it might help others with the issue. I had the work done at Bristol (Cribbs Causeway) Honda and they were excellent.
