Obviously the 120A alternator worked better, but it was still enough.įirst step for better electrical everything would be to do the big 3. I’ve run 1000+W systems in old Rabbits with either 90A or 120A alternators. I’m running a modest 500W stereo system (roughly 30-35A draw), in my sedan and don’t see any indication that the stock charging system is inadequate. 120A is more than enough for the accessories that you mentioned. If your TDI doesn’t have a 120A alternator, it’s been swapped.

How long does a factory alternator last, before it technically dies? Most of the time, all that’s at fault are the brushes, and they’re going to wear at the same rate whether at a limited charge rate or at a full charge rate. The alternator charges 100% of the time that it’s spinning, with its charge rate being limited by the voltage regulator. In addition, I believe some needed to modify the HL housing to fit the drop in’s heatsink and fab assembly. The last time I checked, there was a decent amount of money collectively spent, but nothing that was deemed far superior. There’s also an ongoing thread in the upgrades section about led bulbs. I can guarantee that those aren’t $8 per pair. I’ve seen that video, and a bunch other from the retrofit source. I'm just really hesitant to think that with DOT spec lights there's much to be gained with with going LED, especially at the price point Todd mentioned.

I'll be the first to admit that 55/60W H4 (or 9004 etc) halogen bulbs are not bright compared to current standards, I even run the ones in yellow glass balloons so it's even worse but at least they're in European headlights with a proper cutoff, but DOT lamps from the past are not really designed to accept newer tech even though people install it. I'm hoping law enforcement takes care of his issue so I can use the 'see, I told you so' response. He swears up and down he's not blinding anyone, but when every car on the road flashes you because they can't see it's a big problem. I have a friend who does this and I tell him not to do it, but it makes no difference. Where I have a problem with LED's (or any non-factory spec system) is in cases where headlight illumination technology that was never specified is retrofitted in existing cars and the lamp isn't designed to handle it, like with older DOT spec headlights when someone installs HID's and it blinds the pants off other cars but the owner swears it doesn't. Especially in tails that weren't designed for them, the light looks uneven for tails / parking lights markers etc. I'm not dissing the LED swap, I think some of it is ok but I've never been a big advocate for it, I think in older vehicles LED's can look a little ricey. LED bulbs incl headlights draw = 4-8 amps.Īlternator max generating capacity = 90 amps. More power demand equals more wear and tear.įilament bulbs incl headlights, lights on, draw = 20-40 amps.

When the alternator has to generate less amps and watts because you upgraded to LED lighting, and this is on a constant basis second by second like when your lights are all on at night, then your alternator runs cooler, lasts longer, and has more headroom to generate watts when you really want to use them such as stereo, gps, cabin fan blower, radiator fan, ECU, phone tablet charging, passengers watching tv in the back, everything uses electric power so it’s best to use it as efficiently as possible to go easy on the alternator and its belt which is also under more strain the more Power you demand from the car, and will break esp when you go over bumps while it’s straining and in doing so you threw it some twisted moments of angular momentum from multiple directions.
