Replying to: graybear56 (Jan 29, 2009 12:20 pm) If you think that fuse is good and not blown, then I will need you to check some voltages with the voltmeter, I'll tell you what you'll need to check at that time. Actually if you think that fuse is good, if you either have a spare in the fuse box lid, or there is another fuse of the same 40A size, then swap it anyhow. |

I have already checked that fuse for continuity. It is good.

Replying to: graybear56 (Jan 29, 2009 1:27 pm) Your starter will crank, but it won't start running. Your dome light, headlight, radio don't work. Your horn and flashers do work. Let's start with the the dome light, which doesn't work, and should be easier for you to troubleshoot. It may identify the problem, or a clue to other problems. It get's it's power source from the fuse link block, thru the shorted pin (a wire just to the right of the 7.5A dome fuse, then it goes to an 'integration relay', to the ceiling bulb, back to the integration relay, then to the door switches. This is an integrated circuit, so may have fried but lets check the basics - With the voltmeter, check for 13-14 volts on the shortpin, pull the dome fuse and check for voltage on the one leg where the fuse would plug in. You'd expect voltage on one leg (being fed from the short pin), no voltage on the other leg...which feeds the integration relay. Check to make sure the 7.5A fuse has continuity. You can't really check the integration relay, but now check the dome light itself. You should have voltage on one side of the bulb holder. When the switch is in the ON position, the ON switch actually provides a path to ground, so you should + on one side of the bulb, and nothing on the other. Check to make sure the bulb filament has continuity. "I believe" you should get this bulb to work even if the integration relay might be defective. Assuming that bulb lights with the fuse having voltage and the dome switch in the ON position, then if you switch it to the DOOR position and it doesn't work, then your integrated relay is bad. It's on the back side of the fuse box that is inside the vehicle under the dash, by your left knee. The integrated relay provides the nice controls for the dome light, timed delays when entering and exiting, slow diming, and it monitors the door sensors. |

It gets it's power from the same connection that provides power to the shorted pin mentioned with the dome light. If you have power to the shorted pin, then you should also have power on the one leg of the Radio#1 fuse. In addition for checking that voltage, check to make sure that the fuse has continuity. The 7.5A Rad#2 fuse, gets it's power from one of the internal wipers on the ignition switch AM1. That wiper also provides power to both the 15A cigarette lighter fuse, and the 15A Power Outlet fuse. It's easy to check either of those two outlets for power, and if they have power, then the input to your Rad#2 fuse should also have power. If you do NOT have power on the outlets, then check your 40A AM1 fuse. If power on the outlets, then check the continuity of the 7.5 Rad#2 fuse. Remember the key needs to be in and turned to provide power to this circuit. If you have power on both of those fuses to the radio, and it still doesn't work, your radio is undoubtedly toast. I doubt that you would have had the key in and turned when connecting the battery incorrectly, so the fact that the key wasn't turned would have provided protection to the AM1 side of the power feed thru to the 7.5A fuse. If you have a power problem, I would expect to find it on the 20A fuse supply side. By the way, if AM1 is okay (w/key in on position), I would have you check to be sure the turn signals work, gauge lites up, heater motor blows, and wipers work.

Replying to: kiawah (Jan 29, 2009 4:04 pm) So when you indicate the results of the above, can you tell me whether you have daytime running lights or not in your vehicle. |
