Ok, this sounds like a " Serious, Voltage Drop " ie. lights go dim, and at same time Low voltage to the TCI, and Ignition Coil Primaries. So, I have to assume, that somplace in the electrical system, a component, is turning into a High Resistance short to ground. ( Some amount of resistance, between a dead short, and an open circuit. )

In a 12 Volt DC system, an extra 5 to 20 ohms would act like a Heating Element, and severly drag down the voltage.

OK Quick qestion, can't remember, as I have discussed a lot of problems with different folks lately.

--- What is the condition of your battery? New, Old, if so how many years old ???

---- Why do I ask, you describe this as intermitant, only happens at times, This could be an " Internal High Resistance " INSIDE the battery, between the plates. In an " Old " Battery, sediment builds up in bottom, and can cause an Internal High Resistance between the plates. This would Drag Down the Voltage on the entire system.

---- I will read thru all the past posts, between Us, and your postings, I need to update myself on all your information, and details of work you have done so far.
