I have a 98 Volkswagen TDI with an electrical short somewhere. When I place the key in the ignition and turn to the on position before starting, the display for the odometer and the trip odometer go completely blank and all power is lost. The battery is well charged (though will be replaced if I can get the vehicle started to get it to the repair shop). When I tried to jump start the vehicle the car barely turned over however all power is available to the consuming areas. I noticed that when removing the cables from the terminals that the claps were quite hot and where they touched the plastic case of the battery they melted the plastic. Also the power returns to the odometer and trip odometer after about a minute or more. Can you help me find the short. It seems like something with the ignition switch or the starter but I am unsure as to how to go about it. I have checked the fuses.

Re: Electrical Problem - Ignition Switch?
From what you have written it seems like when the glow plugs are activated the voltage drops to zilch.
I would check the battery terminal connections, the earth (ground) connections to the body / engine, and the wiring to the glow plugs. Those glow plugs draw around 60 Amps!
"When I tried to jump start the vehicle the car barely turned over" suggests a defective circuit to the started motor too. All in all I'd check everything above, but especially the earthing, which is a common factor in all of your symptoms. The battery may well be fine.
If these suggestions do help you solve the problem, please give my reply a rating to help others judge my knowledge / guessing skills. If they do not, please add a comment with more details so I can try to help you further. Cheers, D

The ignition switch is the main electrical switch in your car. When a key is placed inside the ignition and turned, it is supposed to start your vehicle's engine. you may encounter problems with the ignition switch. The process of fixing it is the same for all vehicles. If your Honda has an automatic transmission, make sure it is in park. The key will not turn in the ignition otherwise.
Disconnect the negative battery cable with the proper size wrench and place away from the battery. Insert the key into the ignition lock cylinder and turn the key to the run position. Remove the steering column cover on a tilt steering wheel model by pressing the upper and lower section of the cover together and pulling free from the mounting plate. Remove the steering column covers on a non tilt steering wheel model by using a Philips screwdriver and unscrewing the mounting screws. Disconnect the electrical connector from the ignition switch by lifting up on the release tab and pulling. Press the ignition switch actuator pin by pushing a small screw driver into the key lock cylinder, while doing this pull the ignition switch out of the ignition switch housing.
Insert the new key into the new ignition switch and turn the key to the run position. Insert the new ignition switch into the ignition switch housing. Wiggle the switch back and forth until the actuator pin mounting hole is aligned and falls into place. Install the electrical connector back into the connector housing by pressing it in with your hands. Place the steering column covers back onto the non tilt steering wheel and insert mounting screws. Tighten screws using a Philips screwdriver. Place the steering column covers over the tilt steering wheel and press the upper and lower portion together to snap covers back into the mounting plate. Pull on the ignition key to ensure switch is locked into place. Turn key to the "off" position and remove the key. Insert the key and start the vehicle.
This is caused by a defective ignition start switch, this is the electrical switch that powers up the electrical system when u turn the key, replace that switch. The switch is on the back side of the ignition key cylinder, see picture below, cost is about $20.00 for the switch, easy to replace, just take the plastic covers off the steering column
sounds like a short or loosening wire somewhere - have any "after- market" accessories been added ??? new stereo or amp ?? check these item and there wiring if so. It could also be the ignition switch itself......unfortunately - you may have to wait for a permanent failure to find the cause
sounds like it is a lower ignition switch problem. The upper ignition switch is where you insert the key, The lower is an electrical switch that causes this issue. This car probably has air bags, if so, not recommended for an unlicenced technician.
