(I'm knee deep in tracing and correcting the electrical on my recent project, so bear with me!)
Is there an alternative (read: safe) approach without the engine running? I'd like to do work on things like the lighting, radio, windshield wipers, etc. that obviously require current, without the car running. I'd prefer not to rely on just the battery for this and want to mimic the alternator's output amps for things like the hot-air blower, and the VPC A/C unit.
1. Will this hurt the injection system?
2. Can I disconnect the fuel pump (electrical) without damaging anything?
3. Can you use the "trickle" chargers in lieu of a battery?
4. Are there any products out there that produce the correct amount of current for a car that isn't running?
Words of wisdom from the guys who've all been there/done that are greatly appreciated!
