wow no year car told our country , nor engine, there, or if A/T tranny.
wiring varies greatly by all that in fact. and is first to say.
secondary positive wire
we can;t guess what that means.
using amp clamp ammeter finds all drains and shorts easy.
max drain is 0.050 amps on most cars max.
more than that is in fact class of short, the real name in pure electronics is and overload. OK" easy word to learn and covers it all.
it is overloaded. and drains the battery as all cars do overloaded key off
a real tech uses an AMMETER, or super savvy and AMP clamp meter so we do not need to disconnect wires, pins and worse..
there are 2 main power feeds on cars, (or 3)
1: hot all the time as you just witnessed.
2: key on only power,
3: IOD, my jeep has this Ignition off drain, (we call it computer memory power) the car is shipped from the factory with all IOD fuses pulled.
that is how it works, besides starter feeds. etc.
what tech does is simple really, using REAL tools modern
is connect the ammeter clamp on that huge hot wire. key off
and omg reads 1000mA drain (that is an Illegall drain)
aka overloaded.
we do call it dark current and phantom drains.
and 1000 MA smacks hard as a 1 Lamp stuck on , so look at the car
in pure darkness, to see a lamp stuck on,OMG the silly glove box glows door closed, ETCnot having the manual I and forced to do 2 crazy acts (labor max)
trace every inch of that colored wires, on the whole car, (not me)
or pulled everything (every load) off the the car blind, to see the one that ends DRAIN illegall (bingo found it) the HARD way.
it really is simple with real tools and a real; manual.
the meter to use is is here, DC AMP clamp (not AC only)(
the most cheap ones are NO GOOD, AC only. AMps $15 USELESS here.
$30 gets the goods (must say DC current is offered)<,on the clamp.
2amp low range is best. not 40a low range,only meters.
