Prior my voltage would drop to near redline at in gear idle with all that on.. and a sligjt bump in idle on the gas pedal fixed it.. so i just manually adjusted my idle on the carb.
I also got sylvanias best headlights as well the gold or whatever they are.. They claim to only last 1 year.. but its been 2 for me so far. I also got new fog lights.. someone stripped my stock ones so i ordered some chromed fog lights just regular rectangle ines that use standard fog light bulbs. They are nearly as bright as my headlights lol.
I pointed em up a tad higher on the road a d aimed my headlights slightly higher as well.
Only downside is idle in park is kinda high at like 1100.
Here isa pic of what the lights look like.
You didn't actually fix any problems, you're just burning more fuel. Take a meter out there, and I'll bet you're still getting low voltage at the headlights. The alternator only puts out so much voltage, it's not going to fix a giant resistor (super long headlight circuit). Most people aren't complaining about low headlight voltage and visibility at idle, the problem is when driving down the road, likely at ~2k rpm or more.
aa
well i dont have that problem then. My issue were dim lights at idle.. My headlights are brighter then most cars on the road i noticed look at my pic.. If you complain about that brightness then i dunno what to say. So whatever. My wagoneers headlights are brighter then my 98 ZJ and dont tell me the ZJ has no relays because it does lol.. Im using sylvania basic bulbs in the ZJ and new non cloudy housings vs the gold sylvanias in my wagoneer
Garuntee most of the ppl complaining are using 10-20+ year old headlamps.. My originals that were on the jeep when i got it 3 years ago turned on.. But they were so yellow and dim my mom who was with me when driving at night said to turn my headlights on.. i was like they are on.. lol
So i got the brightest lights sylvania make.. and it was amazing how much brighter they were. Old light bulbs loose their brightness over time and i bet if ppl just replaced em like i did they would be quite surprised.
But sure ill take my headlight out and use a volt meter with someone on the gas at 2k rpm to see whst the voltage is at on the plug and post back with a picture to see if my voltage is low at those rpms..
Any incandescent or halogen bulb looses brightness over the years.. Hell my christmas lights this year the whites i had to replace due to them being yellow and dimmer over a nee set of standard incandescent lights.. my tree looked silly with it being half white and half yellow.
Im not doubting the relays work.. but i do doubt ppl actually replaced their decades old headlights first.. And dont tell me they do because most people assume it turns on so it works fine lol.. And doing this relay harness fix may make em brightee but you still should get new headlights vs using old ass worn out incandescent/halogen bulbs.
I still have my old headlights in storage.. think ill install em and do a before picture to show you what im talking about..
put a new brake light in and see how much brighter one side will be to the old one LOL.. I had to replace all the tailight lamps because new vs old looked silly.. Same with my intrument lights on my ZJ.. one burned out.. got an identical replacement.. Now half my cluster is brighter..
Again im not doubting 13-14v is brighter then 12 or 11v but the relays are only half the problem here.. Why do this fix and say wow so much brighter... Then keep your old ass lights installed.. Get a new set of headlights as well please
edit: Here i checked the voltage going directly to the plug its 13.24v at idle in park.. Not 2k rpm. My battery terminal reads 14v So .76v drop.. But 13.24v isnt low voltage by any means.. Hell ill probly do this relay thing eventually.. but for now Replace your old lamps plz..
