VOLT DROP AT THE COIL!!!!
Hi I own a Mitsubishi Cordia that has been in storage for some time. It wont start and when testing found Only 9V at the coil but after changing to new battery took it up to 11.6V I found the alarm was causing the volt drop so bypassed it and then had 12V at the coil. Then found that even the fuel pump when turned on did the same thing, anything lights, wipers etc would give a slight volt drop from 12.2V to around 11.6V at the coil. Car will not start not even try but as soon as I put 12V straight to the coil starts. would like to find the problem rather than run a new feed. My question is what voltage should you have at the coil when the car is running? Any ideas what might cause this volt drop?
Any info or help would be much appreciated
