Weird Electric Spike w/turn Signal Op + Shift Issue

[gper]

My early car does not get driven much, and recently I found the #1 fuse for the turn sig & brake lights popped.

When I operate the signals now the instrument needles jump & momentarily the gen light flashes on. It looks like the opposite indicator arrow flashes as well.

It settles down immediately and the signals & brake lights operate.

Also, suddenly is clipping reverse on the 1>2 shift. Assume that would be the lock out springs in the shift mech?

Thanks for any thoughts

Still no replies, thought I would give it 1 more shot
Thanks

It may be the flasher relay is failing and overloading the circuit, or there is an intermittent ground on one of the signal housings. The usual suspects: Wire condition, connectors, grounds. Not much else on the early cars.

Tranny is for someone else to provide some ideas.

Replaced the flasher, problem remains.

Checked all the grounds in the signal housings (and several others), they seem fine.

Obviously something grounding/shorting as it will blow the fuse eventually.

Head & tail. running lights operate normally

The shift issue was the round bushing in the shift tunnel, failed into pieces. New rebuild kit from our host and all is well.

The electrical issue is solved, but I really don't know what I did to fix it. Replaced flasher w a generic FLAPS unit that actually made the problem worse (fuse blew quicker) but after a bunch of messing around with grounds and tidying up some old wiring bodges, and putting he original flasher back in, suddenly all is well.

Once you clean off the corrosion by removing and replacing the flasher and clean the grounds up for better contact, those problems generally go away.
