Question about 1990 Honda CRX

Open Question

My crx is blowing ecu fuse on key on and it blows my clock radio fuse to, my fule pump wont prim either. i got a multimeter and have been testing continuity and have found some burnt wires on the connector that leads the wiring to the back of the car. now this all started after i bought a new alternator i have an b18a1 obd0 ecu and i bought the d-series alternator for the year of the car, and when i was driving every time i would reach about 4000rpms my battery light would come on, i drove it for about 15 miles and then bam sparks shot out my clock when i was in first gear at about 4500rpms. blew 5 fuses under the dash and the ecu fuse. replaced all the fuses and now it only blows the ecu fuse and clock radio fuse like i mentioned before. but the burnt wires i found on the one side of the connector there is 2 melted wired from the base of the connector and back as far is i can feel. and on the other side of the connector there was a wire that comes out of the connector and right back in to a slot right next to the spot it comes out of and it was completely melted and the whole wire from end to end and melted to other wires. i taped up that wire and when i test all the wires on that connector for continuity all the burnt wires show good continuity but the yellow white wire that runs from fuel pump to connector and from the connector to injector i think but any way the test is reading 140.1 instead of .4 like it should. I can use all the help i can get im still learning but im learning fast. i have taken my dash. i need to run my own wire and bypass all connectors on all the burnt wires and hope that fixes it. really dont wanna have to get a new harness cause im not completely sure which harness i would get. i have b16a2 block with b18a1 head and half of the **** on it is written in Japanese

SOURCE: Could i use a complete

You would think yes but I doubt this. I have found that manufacturers change the wiring harnesses almost every year. The connectors would fit but there is no way to be sure if they are connecting the correct sensor and wires to the ECU input and output. You could ask a Honda Dealer or shop and they could compare the part numbers. Somewhere on those wiring harnesses there will be a part number and if the part numbers match then yes you could. The major issue is in the actual ECU connection. Again, those connectors could work but because you don't have anyway to verify the wiring by markings this is not a good idea. Other than using that harness to provide wires of the proper size to replace sections of the harness being replaced I would not try a straight up trade unless the dealer confirmed they are interchangeable.

92 geo tracker keeps blowing fuel fuse 15 amp but when I go to a 20 amp it is fine gas tank is haff full of fuel what is my problem

first off each fuse has a name , so what is the correct name, the 92
has 3 EFI fuses, DOME (memory) IG-Coil (ecu and spark) and "FI"
never up the amps ever or burn the wires up. sorry but that is a FACT. the a above data is wrong, this cars pump draws 4amps.
if more its bad, sure if over 15 it blows, but is a bad pump.
all pumps like to do that, they burn up and suck power, like a piggy.
see your fuse here, linked,
this car and ECU nor know for shorted pumps and shorted ECU
the 92 uses these JUNK brand caps, large electrolytic caps.
and they love to short, on all 89 to 95 trackers and sidekicks in usa.
they are marked Rubycon.

so again which fuse?
ill pretend its FI blown

FI is bottom right, lost the cover? now you have one.

is engine 8 valve or 16?, they have different EFI , systems.
Im sure its FI, as it runs ECU and pump. so..... and they love to blow.

ok i throw dice for you, land on 8v.
see 8v FI fuse here?

what i do is remove the left rear tail light,lens.
then see the pink pump wires, I measure the pump current
i reads 4 amps, with helper keying on over and over.
now if near 4amps, then the ECU is shortings it CORNER cap.

the caps dry out,inside, leak acid , wreck copper traces
and then the cap shorts, some times , it loves to short on speed bumps. due to vibration, its just a bad 50 cent part
that any tech can change or any HAM radio guy, etc.
with simple soldering tools and skills
do tell engine type G16a or b (a= 8v, and b = 16v) and we can
point to exact part bad.

Where is the ecu ground on a 2002 4sl rodeo

old post
" ecu wont read bur" ><<<< i can not decode this.
bur, vur,nur, byr,bir, nah, bue, but, ah its BUT? (type analysis, me bad)
ECU won't read ,but fues is good, (test fuse, never just look)
What does wont read mean. by what tool by what actions, by you.?
IF the ECU will not scan with a new scan too the fuses are blown.
period! (or wrong scan tool;) this year is VPW OBD2. (ask)

simple answer, RTM.
long answer.
we cant answer on any car lacking engine size (type) and country.
sorry. can't. and be RIGHT.
in uSA its 3 engine this year.
2.2 L I4
3.2 L V6
3.5 L V6 each can be quite different, post engine.

horn don't blow can be blown fuse. test them. the one marked HORN being first.
can be bad horn relay or bad clockspring. or even a bad horn
to test any horn, HOT wire it. to any 12vdc battery.

ECU issues, gee, what country and engine and what are the Symptoms of your ECU. in details. running or not.
hot or cold, driving or not.

The ECM1 fuse blowing usually indicates that the fuel pump wires shorted inside the tank. If you drop the tank and remove the module, you will probably find the insulation burned off the gray pump wire.

2006 grand cherokee cd player dont work

There are two power sources for your is full time and powers the clock, the other is on the accessory side...only hot with key on. check that power supply. Remember...fuses dont wear out...they blow for a reason. If you find a faulty fuse replace it...if it blows again, it is because there if a fault somewhere.

Fuel ECU fuse keeps blowing (30 amp)

Your fuel pump is internally binding and causing the fuse to blow. Change the pump (and filter while you're back there.)

Keeps blowing electronic controlmodule FUSE?

I have seen this many times in my 30 years as a technician, it is always caused by a shorted engine wiring harness, look around the harness in area's of wear, like where it connects to the engine from the firewall or where is crosses metal like cylinder heads, it will be rubbed through somewhere.
