Dan, I had been contemplating for the last 3 years to change my original Motorola alternator. In the summer with the A/C, the headlights and the wipers on while in creeping in traffic, the DeLorean electric's system just doesn't cut it. I had changed the battery to an Optima battery hoping that will help. It did help -- very little. Last Friday, I had Rob at PJ Grady change my unit to a new digital by Delco with 105 amp output. It is the same size of the original unit. It use the same bracket and a little change int the wiring. It was not cheap, but it is worth the money, every penny of it. It gives the DeLorean a new feel. Now, there is correct and decent electrical power when everything is turn on. No more dimming, especially while creeping in the slow street and highway traffic. It now has a little more life in the ignition's electrical system -- slightly more pep. I am glad I made the change! I hope this personal info helps.
