Every mechanic I talk to says it has to be the alternators since I am getting voltage to the exciter but the alts still aren't charging. I am lost I am going through all the trobble steps again along with cleaning the firewall connection then if I still have nothing I have to accept the fact...

Have not done that yet but will try it tomorrow.

Ok that was just kind of strange to me. I wasn't sure if that was an issue or not.

Ok yes the light is on for gen1 when exciter wire is plugged up. Wasn't sure if that was a issue or not.

Something i did notice last thing is that on gen1 with the exciter wire unplugged im getting 12.7 volts but with it plugged up I only get 4.6both readings are on the exciter wire with the key on not running. Any idea why that is.

Thanks I will go through everything again over the next couple of days I had to go ahead and stop for today. I am at the point of throwing stuff and am just feel like I am being repetitive. I will begin again with a fresh mind and methodical process after work tomorrow. If anyone else has any...

Checked the four fusible links on the distribution block and the one on gen2 all are good. All the fuses are getting power at both sides

Also compared part numbers on the pcb before installation

The pcb came from classic industries and yes the circuit ribbon matches exact. It is the one for the idiot lights. Im stumped to say the least ive had the power probe and multi meter out all day and I am more confused than when I started

Also the charging system wasnt working prior to pcb replacement

No voltage to the socket. Quick note the reason I replaced the pcb is because gen1 light didn't work. Now after replacing it all lights works except the gen2 light

The fuse and relay for gen2 are good and I just replace the pcb for the instrument cluster

Gen1 does gen2 does not. What other fusible links are there other than the 4 on the terminal block and the 1 on gen 2

Both alts tested fine at a reputable auto electrical shop.

Gen 1 running is accurate. Just double checked measuring from ground lug and positive lug on alternator. Gen 2 is measuring 12.7 and 12.7 on both terminals and I just noticed while running my gen 1 light stays dimly lit

Alright i've been through what i can find in the TMs and the sticky. Gen 1 I have 12.7v on red wire and 0 on brown key off 12.7 on brown key on and 12.7 on front battery running or not. Gen2 I have 25v on red 14 on brown key off. Same with key on and 12.8 on rear battery. Running or not. Now...

Hey Warthog I had something baffle me earlier. At my plug on gen1 on the brown wire. If i test it unplugged from the gen with key on engine off i get 12.8v with it plugged in key on engine off i only gey 4.5v any idea why this is. Cant test with the engine on right now I am replacing the...

Already have. I actually replaced them on both alternators last week checked it again after gen2 light didn't work and voltages are good

So pulled the fuse for gen2 and its good. Switched bulbs and bulb holders around still a no go. I guess the next step is to pull down the relay holder and swap out the relays and see if it makes a difference. The only other thing I can think of might be fusible links somewhere.

No problem Dave
